The meeting in Andong, a historic southeastern South Korean city known for its UNESCO-listed folk village, marked the second leg of an unprecedented series of hometown summits between the leaders. In January, Lee traveled to Takaichi’s hometown of Nara, becoming the first South Korean leader to hold a bilateral summit in a Japanese counterpart’s hometown.

South Korea’s presidential office said the latest meeting was intended to reinforce mutual trust and maintain momentum in bilateral ties, while Takaichi said before the talks that cooperation between Seoul and Tokyo was increasingly important given instability in the Indo-Pacific and the Middle East.

The summit agenda included economic and energy cooperation, the impact of the Iran conflict and broader regional security concerns, according to officials from both governments.

Analysts said the meeting reflected a strategic decision by both countries to prioritize coordination over unresolved historical disputes rooted in Japan’s 1910-1945 colonial rule of the Korean Peninsula.

“The two countries put more emphasis on agenda for cooperation than contentious issues,” said Choi Eunmi, a Japan specialist at the Seoul-based Asan Institute for Policy Studies. “They would now think constantly fluctuating or negative bilateral ties won’t be helpful to anyone.”

Relations between South Korea and Japan improved significantly in 2023 after previous administrations sought to move beyond disputes involving wartime forced labor and the issue of so-called comfort women, while strengthening coordination on regional security and supply chain resilience.

Both countries remain key United States allies confronting shared concerns over China’s regional influence and North Korea’s expanding nuclear and missile programs.

Observers initially questioned whether ties would remain stable after Lee, viewed as a political liberal, and Takaichi, known for her conservative nationalist credentials and hawkish security positions, entered office last year. However, the two leaders have maintained frequent engagement and public displays of cooperation.

In August last year, Lee selected Japan as the destination for his first bilateral summit after taking office, an unusual diplomatic move for a South Korean president. During a January meeting in Nara, the leaders participated in a public music session featuring K-pop songs, including BTS’ “Dynamite,” reflecting efforts to project warmer bilateral relations.

Analysts say broader geopolitical shifts have accelerated the rapprochement between Seoul and Tokyo, including concerns over US President Donald Trump and his administration’s trade and security policies, as well as the economic fallout from the Iran conflict.

Both South Korea and Japan have pledged major investments in the United States, while navigating uncertainty linked to tariffs, supply chain disruptions and evolving US security commitments in Asia.
Experts cautioned, however, that unresolved historical grievances could still trigger future tensions if left unaddressed.

“Both countries aren’t talking about how to resolve and prevent recurrences of conflicts over those issues,” Choi said. “We don’t know when they could occur again.”

Speaking in Canberra after talks with Australian Prime Minister Anthony Albanese, Takaichi said both countries would act with urgency to strengthen energy security amid a supply squeeze linked to reduced shipping through the strait.

Roughly one-fifth of the world’s oil typically transits through the Strait of Hormuz, with flows curtailed after Iran throttled shipping following attacks by the United States and Israel. About 80 percent of that oil is destined for Asia, according to the International Energy Agency.

“The effective closure of the Strait of Hormuz has been inflicting enormous impact on the Indo-Pacific,” Takaichi told reporters, adding that Japan and Australia would maintain close communication to respond to the situation.

Both governments said they would seek to enhance resilience and autonomy in energy supply chains. Australia is Japan’s largest supplier of liquefied natural gas, while Japan provides a share of refined fuel products, including diesel, to Australia.

The two sides issued a series of agreements covering energy, economic cooperation, defense and critical minerals. Albanese said the measures would help shield Australia from “global shocks” stemming from conflict in the Middle East.

Japan has also emphasized the importance of securing stable supplies of critical minerals used in semiconductors, electric vehicle batteries and defense systems. Australia has positioned itself as a key supplier of such resources, highlighting its reserves as an alternative to concentrated global supply chains.

Defense cooperation has expanded alongside economic ties, including a deal valued at around Aus$10 billion for Japan to supply Mogami-class stealth warships to the Australian navy.

In a separate foreign policy address in Vietnam over the weekend, Takaichi reiterated Japan’s commitment to a “free and open Indo-Pacific,” a strategy aimed at strengthening regional security and supply chain resilience.

The commitment came during Takaichi’s visit to Hanoi, where the two leaders discussed expanding the Comprehensive Strategic Partnership established in 2023, covering sectors including energy, critical minerals, artificial intelligence, semiconductors and space cooperation.

“The two sides identified economic security as a new priority area for bilateral cooperation,” Takaichi told reporters after the meeting.“With regard to critical minerals, both sides agreed to strengthen close coordination to ensure stable supplies and reinforce supply chains,” she said.

The talks come as Japanese investment flows into Vietnam weakened sharply despite stronger trade ties. New Japanese investment in Vietnam fell about 75% year-on-year to $233 million in the first quarter of 2026, while bilateral trade rose 12.3% to $13.7 billion during the same period, according to Vietnamese government and customs data.

Japan remains one of Vietnam’s largest foreign investors, with major Japanese manufacturers operating extensive production bases in the country across electronics, automotive and industrial sectors.As part of the visit, both governments signed six agreements covering infrastructure development, climate action, agriculture, digital transformation, technology cooperation and space development, reinforcing broader strategic cooperation beyond trade.

Vietnam has also been seeking support from Japan and other partners to stabilize oil supplies as conflict in the Middle East pushes up crude prices and disrupts shipping routes.Under Japan’s $10 billion Power Asia Initiative, designed to strengthen energy self-reliance across Asia, Tokyo will help arrange crude oil supplies for Vietnam’s Nghi Son Refinery and Petrochemical Complex, one of the country’s most important energy facilities, Prime Minister Hung said.

Takaichi is also scheduled to meet To Lam and senior Communist Party leadership later on Saturday and deliver a keynote address at Vietnam National University.Her speech is expected to mark a decade since former Prime Minister Shinzo Abe introduced Japan’s “Free and Open Indo-Pacific” strategy, a regional framework aimed at strengthening rules-based order, maritime security and economic cooperation across Asia.

Vietnam has publicly supported Japan’s regional initiatives, including the Free and Open Indo-Pacific Vision, aligning them with ASEAN’s broader Indo-Pacific outlook and emphasizing international law, regional stability and balanced strategic autonomy.Hung said Vietnam viewed the framework as contributing positively to “peace, stability, cooperation and development in the region and beyond.”

The visit reflects Tokyo’s broader effort to deepen strategic partnerships across Southeast Asia as competition over technology, trade routes, mineral access and energy security intensifies across the Indo-Pacific.

Ukrainian Ambassador to Japan Yurii Lutovinov told Reuters the policy change by Prime Minister Sanae Takaichi was “a very big step forward,” even though Japan still restricts exports to active conflict zones.

“This allows us to talk,” Lutovinov said, adding that any future transfer would require a defense technology agreement between the two countries.Kyiv is also seeking Japanese investment for domestic air-defense systems to reduce dependence on U.S.-made Patriot missiles and is discussing Tokyo’s possible participation in NATO’s arms-funding mechanism for Ukraine.

Japan has linked Ukraine’s security to its own concerns over China’s growing military power and tensions around Taiwan, with Tokyo viewing the war as part of a broader global security challenge.

The Japanese destroyer sailed through the strait from early morning to late afternoon, according to a statement by a Chinese military spokesperson, who said naval and air forces were deployed to observe the vessel throughout its passage.

Japan’s Self-Defense Forces declined to comment on the transit. The passage comes against the backdrop of heightened regional tensions over Taiwan, which claims as its territory despite opposition from ’s government.

Beijing considers the Taiwan issue a core national interest and frequently characterizes it as a “red line” in diplomatic relations. It also asserts sovereignty over the strait, a key international shipping route, and has responded strongly to foreign naval movements in the area.

China’s foreign ministry spokesperson said at a press briefing that the transit represented a “display of force” and accused Japan of compounding earlier tensions with what he described as “mistakes upon mistakes.” He added that China had lodged formal diplomatic protests with Tokyo.

Relations between the two countries have deteriorated in recent months, particularly after remarks by Japanese Prime Minister suggesting that a potential Chinese attack on Taiwan could trigger a Japanese military response.

China’s military had previously tracked a foreign naval transit through the strait in February, when an Australian warship sailed the same route, according to state-backed media reports. The latest incident underscores persistent friction over freedom of navigation and sovereignty claims in one of Asia’s most strategically sensitive waterways.

During his stay in Japan, Macron signed a cooperation roadmap covering critical minerals and defense, and held talks with Prime Minister Sanae Takaichi, alongside a meeting with the imperial couple.

He also praised Europe’s “predictability,” in comments widely interpreted as a contrast with recent U.S. policy decisions.The remarks followed criticism from Trump, who described France as “very unhelpful” in the Iran conflict and made personal jibes at Macron.

The exchange highlights growing transatlantic friction as the war continues to reshape global alliances.Macron’s visit to South Korea comes amid heightened geopolitical and economic uncertainty, particularly linked to disruptions in the Strait of Hormuz, a vital route for global energy supplies.

The waterway’s effective closure has driven up oil prices and strained import-dependent economies across Asia.South Korean President Lee Jae Myung called for deeper cooperation with France in an opinion article, emphasizing collaboration in artificial intelligence, nuclear energy, hydrogen technologies and space.

“In an increasingly fragmented and uncertain international environment, partnerships between democratic nations are becoming strategically essential,” Lee wrote.

Seoul has already introduced a fuel price cap to cushion the economic impact of rising energy costs, marking its first such intervention since 1997.Macron’s itinerary in South Korea includes a bilateral summit with Lee, participation in an economic forum, and a visit to a Korean War memorial honoring French troops.

The trip also features cultural engagements, including a dinner with figures from the country’s film and music industries.

The visit underscores France’s effort to deepen ties in the Indo-Pacific while navigating diplomatic strains with Washington over the direction and handling of the Iran conflict.

An individual claiming to be an active-duty officer of the Japan Self-Defense Forces scaled a wall and entered the Chinese Embassy in Tokyo earlier in the day, Chinese foreign ministry spokesperson Lin Jian said at a regular press briefing.

Lin said the individual admitted the act was illegal and threatened to kill Chinese diplomatic personnel “in the name of God,” prompting what Beijing described as shock and concern over the safety of its staff.

China called on Japan to conduct a thorough investigation, hold those responsible accountable and ensure the security of Chinese embassies and consulates.

JJapan’s defence ministry did not immediately respond to requests for comment regarding the incident or the alleged affiliation of the individual involved.

The incident comes against a backdrop of deteriorating relations between China and Japan. Tensions have risen since Japanese Prime Minister Sanae Takaichi suggested that a potential Chinese attack on Taiwan could prompt a military response from Tokyo.

Japan is also expected to downgrade its description of bilateral ties in an upcoming diplomatic report, citing a series of confrontations over the past year, while Beijing has reiterated calls for Tokyo to withdraw what it views as provocative remarks.

Speaking on a Fuji TV programme, Motegi said such a move would be contingent on a “complete ceasefire” and the presence of naval mines obstructing navigation. He described the scenario as hypothetical, adding that minesweeping could be considered if maritime protection conditions required it.

Japan’s ability to deploy forces overseas is restricted by its postwar pacifist constitution, though security legislation enacted in 2015 allows the use of the Self-Defense Forces if an attack on a close partner threatens Japan’s survival and no alternative measures are available.

Motegi said Tokyo has no immediate plans to negotiate specific arrangements for stranded Japanese vessels to transit the waterway, stressing instead the importance of restoring conditions that allow safe passage for all ships.

Japan relies on the Strait of Hormuz for roughly 90% of its oil imports, underscoring the strategic importance of the route. The strait has been largely closed by Iran during the ongoing conflict, now in its fourth week, contributing to a surge in global oil prices.

The disruption has prompted Japan and other countries to release oil from strategic reserves to stabilise supply.

Iranian Foreign Minister Abbas Araqchi said on Friday he had discussed with Motegi the possibility of allowing Japanese-linked vessels to pass through the strait, according to Japan’s Kyodo news agency.

Meanwhile, U.S. President Donald Trump met Japanese Prime Minister Sanae Takaichi in Washington on Thursday and urged Japan to increase its role in efforts to reopen the waterway. Takaichi said she briefed Trump on the scope of support Japan could provide under its legal framework.

Speaking on a Fuji TV programme, Motegi said minesweeping could be an option if naval mines obstruct shipping lanes following a “complete ceasefire,” stressing that any such step would depend on conditions stabilising in the waterway, a conduit for roughly a fifth of global oil shipments.

Japan’s potential involvement would be constrained by its postwar pacifist constitution, which restricts military activity abroad. However, security legislation enacted in 2015 allows overseas deployment of the Self-Defense Forces if a crisis threatens Japan’s survival and no alternative measures are available.

Motegi said Tokyo had no immediate plans to pursue arrangements to secure passage specifically for Japanese vessels, but emphasised the importance of restoring safe navigation through the strait. Japan relies on the route for around 90% of its oil imports, leaving it highly exposed to disruptions.

The near-closure of the Strait of Hormuz amid the ongoing conflict has contributed to a surge in global oil prices, prompting Japan and other countries to release crude from strategic reserves.

Iranian Foreign Minister Abbas Araghchi told Japan’s Kyodo news agency he had discussed with Motegi the possibility of allowing Japan-linked vessels to transit the strait.U.S. President Donald Trump has urged allies, including Japan, to increase their role in securing the waterway, though Tokyo has so far signalled limits based on its legal framework.

Prime Minister Sanae Takaichi said she had briefed Trump on the scope of support Japan could provide under domestic law.

Separately, Motegi said one of two Japanese nationals detained in Iran had been released on Wednesday and would return to Japan. He said the release followed repeated diplomatic representations to Tehran, while confirming that a second Japanese citizen remains in custody.

The exchange was seen as an important step in reassuring Tokyo of continued U.S. support during a moment of heightened regional tension.

Takaichi had earlier remarked in parliament that a potential Chinese attack on Taiwan could prompt Japanese military action.

Her comment triggered a strong reaction from Beijing, including a suspension of group travel to Japan and sharp diplomatic criticism.

Taiwan sits just over 100 kilometres from Japanese territory, and its security situation directly influences Japan’s strategic environment.

China continues to claim Taiwan as its own, while the island’s government rejects this position and insists its future must be determined only by its own people.

Trump has not publicly addressed the diplomatic dispute, leading some analysts in Japan to express concern about Washington’s position.

However, following the call, Takaichi stressed that the U.S. president assured her of a close working relationship and encouraged her to reach him anytime.

She said Trump initiated the call and briefed her on the status of U.S.-China relations, including his recent discussion with Chinese President Xi Jinping.

According to Takaichi, Trump highlighted ongoing dialogue with Beijing and reaffirmed strong bilateral ties between Washington and Tokyo.

Meanwhile, Xi conveyed to Trump that Taiwan’s “return” is central to China’s long-term vision, according to official reports from Beijing.

Trump later noted progress in trade discussions with China but did not publicly mention any Taiwan-related issues.

Japanese officials were relieved that Trump contacted Takaichi shortly after his call with Xi.

Government sources described the timing as significant, reflecting Japan’s continued priority in U.S. foreign policy considerations.

Taiwan’s Premier Cho Jung-tai reiterated that returning to China is not an option for the island’s 23 million residents.

Japan’s Chief Cabinet Secretary Minoru Kihara also emphasised that stable U.S.-China relations are vital for the wider international community, including Japan.

Japan continues to strengthen its defence capabilities as regional competition intensifies.

Encouraged by the U.S., Tokyo has expanded military spending and positioned new defence units closer to Taiwan.

China criticised Japan’s plans to deploy a medium-range missile unit to Yonaguni, the island nearest Taiwan.

Beijing described the move as an attempt to escalate tension and provoke confrontation in the region.

Japan recently scrambled a fighter jet after detecting a Chinese drone flying near its southwestern islands.

These incidents underline the increasingly complex security dynamics Tokyo is navigating.

While Takaichi has refused to retract her remarks on Taiwan, Japan insists it is open to dialogue with China at all levels.

Diplomatic meetings have continued, including talks between Japan’s vice foreign minister and China’s ambassador in Tokyo.

However, China declined the possibility of a meeting between Takaichi and Premier Li Qiang during the recent G20 summit.

Analysts believe this signals a difficult period ahead for Japan-China relations under Takaichi’s leadership.

Some Japanese officials also remain cautious about Trump’s long-term stance on Taiwan.

Analysts note that the U.S. administration could prioritise trade negotiations with China in ways that may affect regional security calculations.

A senior professor of U.S. politics in Japan wrote that understanding these risks is essential for shaping Japan’s approach to China.

Tokyo’s foreign minister stated that the government is not worried about Trump’s silence, noting the U.S. does not comment on every issue publicly.

Japan continues to balance diplomacy, defence, and regional partnerships as it faces one of the most sensitive geopolitical challenges in East Asia.

The recent call between Takaichi and Trump aims to reassure Japanese policymakers as tensions with Beijing remain unresolved.
