Premier Cho Jung-tai (卓榮泰) made a surprise appearance on Saturday at the Tokyo Dome — accompanied by Representative to Japan Lee Yi-yang (李逸洋), Minister of Sports Lee Yang (李洋) and Chinese Professional Baseball League commissioner Tsai Chi-chang (蔡其昌) — to watch the World Baseball Classic (WBC) match. His presence might have boosted the morale of the Taiwanese team, who went on to thrash the Czech Republic 14-0.
Cho’s appearance is the first time an incumbent Taiwanese premier has visited Japan since Taipei and Tokyo severed diplomatic ties in 1972, with the Asahi Shimbun running the story on its front page. There are at least four layers of significance revealed by Cho’s trip.
First is the continued warming of Taiwan-Japan exchanges. Visits to Japan by high-ranking Taiwanese officials have become increasingly frequent in the past few years. In 2022, then-vice president William Lai (賴清德) made a condolence visit following the assassination of former Japanese prime minister Shinzo Abe and former vice premier Cheng Wen-tsan (鄭文燦) visited the following year. Minister of Foreign Affairs Lin Chia-lung (林佳龍) visited in July last year, while Legislative Speaker Han Kuo-yu (韓國瑜) visited in September. Although these visits do not have formal diplomatic status, they represent unofficial exchanges that have been inching forward amid pressure from China.
Second is a softening attitude within the Japanese Ministry of Foreign Affairs. The unit in the ministry that handles Taiwan affairs falls under the First China and Mongolia Division of the Asian and Oceanian Affairs Bureau, alongside Hong Kong and Macau. Because many bureaucrats within that unit view posts in China as a key career objective, they often exercise caution in Taiwan-Japan exchanges, carefully observing China’s reactions. As regional circumstances have changed and Taiwan-Japan interactions have deepened, the attitude of these bureaucrats toward Taiwan has softened as well.
Next is strong backing from Japanese Prime Minister Sanae Takaichi. As Taiwan and Japan do not maintain formal diplomatic relations, Japan places certain restrictions on visits by incumbent Taiwanese officials. That Cho was able to visit Japan last weekend, under the watchful eye of China, would likely not have been possible without Takaichi’s tacit support. This small sign illustrates a broader trend — the Takaichi administration has already made changes in its Taiwan policy.
Lastly is the success of nemawashi — in which people first lay the groundwork for consensus through private, behind-the-scenes communication before any formal decision is publicly announced — diplomacy. According to informed sources, the key players behind this instance of nemawashi diplomacy were Taiwan-Japan Relations Association chairman Frank Hsieh (謝長廷) and Japan’s Liberal Democratic Party executive secretary-general Koichi Hagiuda. In particular, Hsieh has been making frequent visits to Japan to facilitate the trip. He shares a strong rapport with Cho as the latter’s former superior. Lee acted as an intermediary, coordinating other matters behind the scenes and allowing this low-key diplomacy to be fully realized.
As Japan-China relations gradually become more fraught, Takaichi is preparing a visit to the US and US President Donald Trump is preparing for a visit to China, bureaucrats within Japan’s Ministry of Foreign Affairs would ordinarily advise Taiwan to back down to avoid complications. Instead, Japan facilitated Cho’s visit to Japan. This could indicate that Japan is acting with growing confidence and gradually removing political barriers — the symbolic significance of which is self-evident.
The idea that Taiwan and Japan are “as close as lips and teeth” — to use the Chinese expression — was once a common political slogan. Today, as the level of exchanges continues to rise and mechanisms for cooperation take shape, Taiwan-Japan relations are being transformed into an institutionalized community of shared destiny.

The conflict in the Middle East has been disrupting financial markets, raising concerns about rising inflationary pressures and global economic growth. One market that some investors are particularly worried about has not been heavily covered in the news: the private credit market. Even before the joint US-Israeli attacks on Iran on Feb. 28, global capital markets had faced growing structural pressure — the deteriorating funding conditions in the private credit market. The private credit market is where companies borrow funds directly from nonbank financial institutions such as asset management companies, insurance companies and private lending platforms. Its popularity has risen since
The Donald Trump administration’s approach to China broadly, and to cross-Strait relations in particular, remains a conundrum. The 2025 US National Security Strategy prioritized the defense of Taiwan in a way that surprised some observers of the Trump administration: “Deterring a conflict over Taiwan, ideally by preserving military overmatch, is a priority.” Two months later, Taiwan went entirely unmentioned in the US National Defense Strategy, as did military overmatch vis-a-vis China, giving renewed cause for concern. How to interpret these varying statements remains an open question. In both documents, the Indo-Pacific is listed as a second priority behind homeland defense and
Every analyst watching Iran’s succession crisis is asking who would replace supreme leader Ayatollah Ali Khamenei. Yet, the real question is whether China has learned enough from the Persian Gulf to survive a war over Taiwan. Beijing purchases roughly 90 percent of Iran’s exported crude — some 1.61 million barrels per day last year — and holds a US$400 billion, 25-year cooperation agreement binding it to Tehran’s stability. However, this is not simply the story of a patron protecting an investment. China has spent years engineering a sanctions-evasion architecture that was never really about Iran — it was about Taiwan. The
After “Operation Absolute Resolve” to capture former Venezuelan president Nicolas Maduro, the US joined Israel on Saturday last week in launching “Operation Epic Fury” to remove Iranian supreme leader Ayatollah Ali Khamenei and his theocratic regime leadership team. The two blitzes are widely believed to be a prelude to US President Donald Trump changing the geopolitical landscape in the Indo-Pacific region, targeting China’s rise. In the National Security Strategic report released in December last year, the Trump administration made it clear that the US would focus on “restoring American pre-eminence in the Western hemisphere,” and “competing with China economically and militarily
