India’s External Affairs Minister Subrahmanyam Jaishankar hosted U.S. Secretary of State Marco Rubio, Australian Foreign Minister Penny Wong and Japanese Foreign Minister Toshimitsu Motegi for talks focused on recent developments across the Indo-Pacific and ways to advance cooperation among the four countries, according to India’s foreign ministry.

The meeting took place against a backdrop of heightened geopolitical tensions across Asia and ongoing concerns among Quad members about China’s growing military and economic footprint in the Indo-Pacific. The grouping has increasingly emphasized cooperation on maritime security, resilient supply chains, critical technologies and strategic infrastructure.

Officials were also expected to discuss the conflict involving Iran and disruptions to energy shipments through the Strait of Hormuz, a critical artery for global oil and gas trade.

The Quad has repeatedly expressed concern over Chinese activities in the South China Sea, where Beijing has asserted extensive territorial claims and expanded its military presence. China has rejected accusations of coercive behavior, saying its military posture is defensive and aimed at safeguarding what it considers sovereign rights. Beijing has also criticized the Quad, describing it as an effort to contain China’s rise and regional influence.

The talks came days after U.S. President Donald Trump visited China, a trip closely watched in New Delhi and other regional capitals for indications of any shift in Washington’s approach toward Beijing.

Rubio, who arrived in India on Saturday, said Washington wants the Quad to evolve beyond a consultative forum and pursue more tangible cooperation, including on maritime security and critical minerals. He also said officials were working toward a summit of Quad leaders later this year, though no date has been announced.

The four countries had previously aimed to hold a leaders’ summit in India last year, but the plan was postponed amid strains in U.S.-India relations, including disagreements over trade tariffs.

The Quad has emerged as one of the Indo-Pacific’s most prominent strategic partnerships, with members seeking closer coordination on regional security and economic resilience as competition between China and Western-aligned powers intensifies.

Taiwan’s Ministry of National Defense said it detected 21 Chinese military aircraft, including J-16 fighter jets and unmanned aerial vehicles, operating around Taiwan on Monday alongside Chinese naval vessels participating in what Beijing describes as a joint combat readiness patrol.

The patrol marked the second such operation within a week and came as Taiwan remains alert to potential shifts in Chinese military behavior following discussions on Taiwan between Chinese President Xi Jinping and U.S. President Donald Trump during Trump’s recent visit to Beijing.

China claims Taiwan as part of its territory and has steadily increased military pressure on the island through frequent deployments of warships and military aircraft. Taiwan’s government rejects Beijing’s sovereignty claims and maintains that only the island’s people can determine their future.

According to Taiwan’s defense ministry, the Chinese aircraft and naval vessels operated around multiple sectors of the island before the patrol concluded. Taipei responded by dispatching ships and combat aircraft to monitor the movements and maintain surveillance.

The ministry also released images captured by Taiwanese forces, including photographs from an F-16 fighter showing two Chinese aircraft flying near a Y-20 aerial refueling tanker. Additional images showed the Chinese guided-missile destroyer Yinchuan and a Taiwanese sailor observing the vessel through binoculars.

Speaking in Taipei on Tuesday, Pan Chun-kuang of the defense ministry’s intelligence department said the latest patrol had ended but stressed that Taiwan continued to monitor Chinese military activities in surrounding waters and airspace.

Pan said Taiwan was closely tracking the movements of China’s aircraft carrier Liaoning in the Western Pacific and would provide additional information on Chinese deployments when necessary.

The latest operation followed a similar Chinese readiness patrol conducted last Tuesday, one day before Taiwan President Lai Ching-te marked the second anniversary of his administration. Beijing has repeatedly labeled Lai a separatist and has rejected his offers for dialogue.

Military activity has also extended beyond the Taiwan Strait. Over the weekend, Taiwan’s coast guard reported an encounter with a Chinese coast guard vessel near the Taiwan-controlled Pratas Islands, a strategically important outpost in the northern reaches of the South China Sea.

Separately, Taiwan National Security Council Secretary-General Joseph Wu said on social media that approximately 100 Chinese vessels were operating within the so-called first island chain, a strategic maritime corridor stretching from Japan through Taiwan to the Philippines.

China’s Ministry of National Defense did not immediately comment on Taiwan’s account of the patrol.

The increased tempo of Chinese military operations reflects Beijing’s continued effort to assert its claims over Taiwan while testing the island’s defensive readiness and signaling its opposition to any moves it perceives as supporting Taiwanese sovereignty.

Joseph Wu, secretary-general of Taiwan’s National Security Council, said in a post on X that the deployment had taken place over the past few days following U.S. President Donald Trump’s meeting with Chinese President Xi Jinping in Beijing. Wu said China was undermining the status quo and threatening peace and stability in the region.

A Taiwan security official, speaking on condition of anonymity, told AFP that Chinese vessels had been detected before the Beijing summit but that the number operating in the region had risen above 100 in recent days.

China, which views democratically governed Taiwan as part of its territory, has repeatedly stated that it reserves the right to use force to bring the island under its control.

Taiwan rejects Beijing’s sovereignty claims and maintains that only its people can determine the island’s future.The reported increase in Chinese maritime activity came days after Trump referred to “the Taiwan problem” when asked whether he would discuss arms sales with Taiwanese President Lai Ching-te.

Trump said he would speak with Lai and noted that he had held what he described as a productive meeting with Xi during his state visit to China.“We’ll work on that, the Taiwan problem,” Trump said on Wednesday.

Taiwan has frequently reported heightened Chinese military and coast guard operations around the island, activities that Taipei says are aimed at increasing pressure on its government and testing regional security responses.

The latest deployment, according to Taiwanese officials, extended across multiple strategic waterways in East Asia, underscoring Beijing’s expanding maritime presence at a time of heightened geopolitical scrutiny in the Taiwan Strait and surrounding seas.

Rubio’s visit comes as the United States works to ease tensions with India following tariff measures imposed by President Donald Trump that affected several Indian exports and prompted concerns in New Delhi about the future direction of bilateral economic ties.

Speaking before his departure, Rubio described India as a key partner for the United States and emphasized the importance of continued cooperation between the two countries across a range of strategic and economic issues.

The secretary of state arrived in Kolkata on Saturday and is scheduled to begin a multi-city tour that includes visits to Agra and Jaipur. He will also visit the headquarters of the Missionaries of Charity, the religious order founded by Mother Teresa.

During his stay, Rubio is expected to hold bilateral talks with India’s External Affairs Minister Subrahmanyam Jaishankar and meet Prime Minister Narendra Modi to discuss regional security, economic cooperation and broader geopolitical developments.

The centerpiece of the visit will be Tuesday’s ministerial meeting of the Quadrilateral Security Dialogue in New Delhi, bringing together foreign ministers from India, the United States, Australia and Japan.

The Quad has increasingly focused on maritime security, regional stability and maintaining a free and open Indo-Pacific. Member countries have repeatedly expressed concern over China’s actions in the South China Sea and other contested waters, arguing that such activities risk undermining regional stability.

China rejects those accusations, maintaining that its military posture is defensive and aimed at protecting what it considers sovereign interests. Beijing has also criticized the Quad, portraying it as an effort to constrain China’s growing economic and strategic influence.

Rubio has placed significant emphasis on the Quad since taking office. His first formal international engagement after assuming the role was a series of meetings with foreign ministers from the other Quad member states, highlighting the grouping’s central role in U.S. Indo-Pacific strategy.

The Philippine Coast Guard said it deployed aircraft on Wednesday to monitor the Chinese research ship Xiang Yang Hong 33 near Iroquois Reef in the Spratly Islands, where it observed the vessel launching a service boat toward the reef.The coast guard said the operation “confirmed ongoing unauthorized marine scientific research activities” within waters over which the Philippines claims sovereign rights and jurisdiction.

Iroquois Reef lies at the southern edge of Reed Bank, an area believed to contain substantial natural gas and oil reserves and long viewed as strategically significant for Manila’s energy security.

During the aerial patrol, Philippine authorities also reported spotting 41 vessels identified as part of China’s “maritime militia” anchored near Iroquois Reef and around Thitu Island, a Philippine-controlled outpost in the Spratlys inhabited by about 400 civilians and home to a recently established coast guard station.“The Philippines has not granted such consent to the People’s Republic of China for any marine scientific research activities in these waters,” the coast guard said in a statement.

It added that the presence of the research vessel alongside the concentration of Chinese maritime militia ships represented “a serious infringement on Philippine sovereign rights and maritime jurisdiction.”China’s embassy in Manila defended the activities, reiterating Beijing’s longstanding claim of “historic rights” over much of the South China Sea and asserting that the islands and reefs concerned were Chinese territory.

The embassy said Chinese research vessels had carried out their missions “in accordance with international law.”The Xiang Yang Hong 33, a research vessel capable of supporting deep-sea submersible operations, departed China more than three weeks ago and has since been tracked near several Philippine-claimed features in the Spratly chain, including Sabina Shoal and Second Thomas Shoal, both recurring flashpoints between the two countries.

Tensions between Beijing and Manila have intensified in recent years as China expanded coast guard, naval and maritime militia deployments across the contested waterway, where competing territorial claims overlap with key shipping lanes and potentially resource-rich seabeds.

China claims nearly the entire South China Sea despite a 2016 ruling by the Permanent Court of Arbitration in The Hague that found Beijing’s sweeping claims had no legal basis under international law. China has rejected the ruling.

The live-fire drill, part of the annual “Balikatan” exercises, was conducted about 75 km off the coast of Paoay in northern Philippines. Philippine military officials said two missile volleys hit the target ship, the BRP Quezon, within six minutes of launch.

Japan’s Defense Minister Shinjiro Koizumi and Philippine Defense Secretary Gilberto Teodoro observed the exercise on site, while President Ferdinand Marcos Jr. monitored the operation via live feed from Manila, according to the Philippine government.

The exercise coincided with ongoing talks between Tokyo and Manila on a potential transfer of defense equipment, following Japan’s decision to ease restrictions on military exports. Discussions include the possible provision of Abukuma-class destroyers and TC-90 aircraft to the Philippines, Koizumi said.

In a statement, the Philippine military said the drill demonstrated coordinated maritime strike capabilities among allied forces and underscored efforts to enhance interoperability and regional security, particularly in safeguarding freedom of navigation.

The Type 88 missile system, designed for coastal defense, was deployed as part of broader efforts to deter maritime threats in contested waters.More than 17,000 troops are participating in this year’s Balikatan exercises, including approximately 10,000 from the United States and around 1,400 from Japan.

Several countries, including Australia, Canada, France and New Zealand, are taking part as active participants for the first time, reflecting expanding defense cooperation.

Earlier in the exercises, US and Philippine forces deployed the NMESIS anti-ship missile system in Batanes province near Taiwan, amid rising regional tensions linked to competing territorial claims.

China has repeatedly criticized such joint drills, saying they escalate tensions in the region.

The visit by Ocean Affairs Council Minister Kuan Bi-ling to Taiping Island marks the first ministerial trip to the outpost in seven years, Taiwan’s Central News Agency reported. The island is part of the disputed Spratly Islands, claimed by Taiwan, China, Vietnam and the Philippines.

Taiwan’s coast guard said the exercises included humanitarian rescue drills, medical evacuation simulations, and pollution response operations. In one scenario, armed special forces practiced boarding a cargo vessel that had refused to respond to communications.

Authorities said the vessel was escorted to Taiping Island for inspection after it was deemed to have entered waters under Taiwan’s jurisdiction.Video released by the coast guard showed armed personnel entering a ship’s control room while instructing crew members to comply with inspection procedures.

The drills underscore Taiwan’s efforts to assert its presence in the contested maritime region, where overlapping territorial claims have heightened tensions for years.China claims most of the South China Sea and has built extensive artificial islands and military installations in the region, raising concerns among regional states and the United States.

Beijing maintains that its construction and deployments are within its sovereign rights.Taiwan also maintains control over other features in the region, including the Pratas Islands in the northern South China Sea, while Chinese military aircraft and naval vessels regularly operate near Taiwan in what Taipei describes as pressure tactics.

Taiping Island has infrastructure capable of supporting military resupply flights and a port upgraded in 2023 to accommodate larger patrol vessels, though it remains lightly defended compared to nearby Chinese-held installations.

The South China Sea remains one of the world’s most strategically important waterways, carrying trillions of dollars in annual trade and containing key fishing grounds and potential energy resources, making it a persistent flashpoint for regional and global powers.

The Philippines becomes the 13th member of Pax Silica, a programme designed to safeguard the full spectrum of the technology supply chain, including critical minerals, advanced manufacturing, computing and data infrastructure.

The initiative forms part of the Trump administration’s broader economic strategy to reduce reliance on rival nations and deepen coordination among allied partners. Other participating countries include Australia, Finland, India, Qatar, South Korea and Singapore.

The planned industrial hub will be located within the Luzon Economic Corridor, a key economic zone encompassing Manila and surrounding regions with established manufacturing capacity. The Philippines, Japan and the United States have also committed to increasing infrastructure investment in the corridor under a trilateral framework agreement.

“It is intended to serve as a staging point for a purpose-built platform for allied manufacturing,” the State Department said, adding that both countries aim to reinforce supply chains across semiconductors, electronics and other critical sectors.

The project underscores strengthening ties between Manila and Washington under President Ferdinand Marcos Jr., who has moved to deepen cooperation with the United States.

The Philippines, a former U.S. colony, has also taken on strategic importance in Washington’s efforts to counter China’s assertiveness in the South China Sea.

Emphasizing peace, cooperation, and regional stability, Chinese officials reaffirmed the country’s commitment to resolving differences through diplomatic channels rather than confrontation.

According to China’s Ministry of Foreign Affairs, the appeal was made after reports of a minor clash between Chinese and Philippine vessels near Sandy Cay, a small coral reef within the Spratly Islands.

The area, long contested by multiple nations, remains a sensitive zone for maritime navigation and resource exploration. Chinese Foreign Ministry spokesperson Lin Jian urged all parties to avoid actions that could heighten tensions, saying that China remains focused on “safeguarding peace, promoting dialogue, and ensuring the safety of all maritime routes in the region.”

A Call for Dialogue and Stability

Lin Jian reiterated China’s stance that maintaining regional stability and mutual respect should be the guiding principle for managing maritime disputes. He called on the Philippines to work with Beijing toward peaceful and constructive dialogue, noting that both nations share a long history of cultural, economic, and social ties.

“China hopes that the Philippines will stop actions that complicate the situation and instead return to the path of cooperation and consultation,” Lin said during the press briefing.

He emphasized that China’s efforts in the South China Sea are primarily aimed at safeguarding its territorial sovereignty and ensuring safe navigation, not at provoking conflict.

The spokesperson also highlighted that the Chinese Coast Guard and relevant authorities have acted with restraint and professionalism, focusing on preventing escalation and ensuring the safety of all personnel at sea.

This statement aligns with China’s consistent position that disputes should be managed under the framework of regional peace and international law, especially through mechanisms such as the Code of Conduct for the South China Sea, currently being negotiated between China and ASEAN member states.

Focus on Peaceful Development

In recent years, Beijing has repeatedly underlined its commitment to peaceful development and regional cooperation. China has been actively working with neighboring countries on initiatives that promote trade, connectivity, environmental protection, and joint maritime research.

Despite differing territorial claims, China continues to stress that disputes should not overshadow broader cooperation or economic growth in the Asia-Pacific region.

Analysts believe that China’s latest statement reflects a measured and diplomatic approach to the ongoing tensions. Rather than escalating rhetoric, Beijing is choosing to highlight the importance of mutual understanding and dialogue.

The South China Sea, one of the world’s busiest maritime trade routes, carries enormous strategic and economic importance — making stability in the region vital not just for claimant states but for the global economy.

Strengthening Regional Trust

The incident near Sandy Cay comes at a time when both China and the Philippines are seeking ways to rebuild trust and cooperation. The two nations have engaged in regular diplomatic consultations and previously cooperated on joint initiatives in areas such as fisheries management, coast guard communication, and environmental protection.

China’s call for dialogue reinforces its view that regional issues should be resolved among regional partners, without external interference.

Observers note that China’s foreign policy underlines non-confrontation and mutual benefit, particularly with neighboring ASEAN countries. Beijing’s consistent message has been that peaceful negotiation, rather than confrontation, is the most effective way to manage complex maritime issues.

A Positive Outlook for Peace

While maritime tensions continue to test regional relations, the tone of China’s latest response offers hope for constructive diplomacy and peaceful coexistence. By urging restraint and cooperation, China is signaling that it remains open to dialogue and practical solutions that uphold peace, security, and shared prosperity.

The latest developments serve as a reminder that diplomacy remains the most effective path forward. With careful negotiation and continued engagement, both China and the Philippines can contribute to a more stable, cooperative, and prosperous Asia-Pacific region, setting a positive example for peaceful conflict resolution in the modern world.
