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.

Cheng, chair of the opposition Kuomintang (KMT), is expected to travel from April 7 to 12, visiting cities including Beijing, Shanghai and Jiangsu, according to party officials.

Outreach contrasts with ruling party stanceThe visit highlights a divergence between the KMT and Taiwan’s ruling Democratic Progressive Party, led by President Lai Ching-te, whom Beijing has refused to engage and labels a “separatist.”

China maintains that Taiwan is part of its territory and has increased political and military pressure on the island, while continuing to engage with opposition figures seen as more open to dialogue.

Cheng has said improving ties with Beijing does not equate to weakening relations with Washington, stressing the need for stability across the Taiwan Strait.

Timing ahead of Trump visitThe trip comes weeks before Trump is expected to travel to China for talks with Xi, placing Taiwan at the center of broader U.S.-China strategic discussions.

Separately, a bipartisan group of U.S. lawmakers is also planning visits to Taiwan and the region ahead of the summit, reflecting Washington’s continued engagement despite tensions with Beijing.

Taiwan’s Vice President Hsiao Bi-khim has made a rare and symbolic visit to Belgium, where she delivered an inspiring address to members of the European Parliament.

The visit marked one of the highest-level exchanges between Taiwan and Europe in recent years and reflected Taipei’s growing efforts to expand its international presence despite ongoing opposition from Beijing.

Hsiao’s trip to Brussels was centered around her participation in the Inter-Parliamentary Alliance on China’s annual summit, where lawmakers from various nations gathered to discuss human rights, global democracy, and the challenges posed by authoritarian governance.

In her speech, Hsiao drew strong parallels between Taiwan’s determination to preserve democracy and Europe’s long-standing commitment to protecting freedom and human dignity.

“Europe has defended freedom under fire, and Taiwan has defended democracy under pressure,” Hsiao declared, earning praise from European lawmakers who commended Taiwan’s resilience in maintaining its democratic institutions despite constant pressure from China

“I stand here as a voice for a society deeply committed to the ideals that animate parliaments of democracy around the world,” she added.

The visit represents Taiwan’s growing confidence in asserting its democratic identity on the world stage.

While Taiwan’s only formal diplomatic partner in Europe remains the Vatican, many European countries such as France, Lithuania, Poland, and the Czech Republic have increasingly shown willingness to engage with Taiwan through informal but meaningful exchanges.

These interactions demonstrate Europe’s acknowledgment of Taiwan as a democratic partner that upholds shared values of freedom, human rights, and rule of law.

China’s reaction to the visit was predictably sharp. The Chinese Mission to the European Union issued a statement condemning Hsiao’s presence in Brussels, describing it as a “serious violation of the one-China principle” and accusing the island of undermining mutual trust between Beijing and the EU.

However, Taiwan’s government has firmly rejected Beijing’s claims, asserting its right to engage freely with the international community.

Taiwan’s presidential office emphasized that the vice president’s trip was part of ongoing diplomatic outreach to strengthen global partnerships.

Accompanied by Foreign Minister Lin Chia-lung, Hsiao underscored that Taiwan’s participation in global conversations is both legitimate and necessary.

She noted that, despite being excluded from many international organizations, Taiwan continues to contribute to global development, humanitarian aid, and sustainability initiatives.

“Despite being excluded from international organizations, Taiwan has stepped up,” Hsiao stated. “We contribute to humanitarian aid and uphold global standards even when we are not allowed a seat at the table.”

Her message resonated with many in attendance, reinforcing Taiwan’s image as a responsible global actor committed to peace and cooperation.

Hsiao also highlighted the importance of stability across the Taiwan Strait, calling it a cornerstone of global prosperity. Her remarks reflected Taipei’s desire to maintain peace while promoting dialogue and mutual respect, even as China continues to increase its military and diplomatic pressure on the island.

The vice president’s visit follows a broader pattern of Taiwan’s increasing diplomatic activity in Europe. In September, Foreign Minister Lin visited Austria, the Czech Republic, Poland, and Italy to deepen bilateral cooperation.

Former President Tsai Ing-wen is expected to visit Berlin next week to deliver a keynote address on democratic resilience and transatlantic unity.

These growing exchanges between Taiwan and European nations suggest a subtle but significant shift in global geopolitics. European countries are showing greater openness to engaging with Taiwan as part of their broader commitment to supporting democracies under threat.

While most European governments continue to adhere to the one-China policy formally, their willingness to interact with Taiwanese leaders reflects a pragmatic approach to international relations and a recognition of Taiwan’s contributions to global progress.

Hsiao Bi-khim’s visit thus stands as a powerful symbol of Taiwan’s diplomatic determination. It illustrates how the island, despite diplomatic isolation, continues to find meaningful ways to participate in the global dialogue on democracy, innovation, and peace.

For many observers, her presence in Brussels marks a new chapter in Taiwan-Europe relations — one grounded in shared principles, mutual respect, and a collective belief in the value of freedom.
