China has been making endless claims that Taiwan has been a part of Chinese territory since ancient times and Taiwanese have been using ancient and vaguely worded Chinese documents to try and prove that the Diaoyutai Islands (釣魚台) belong to Taiwan.
While these documents may be interesting, they are devoid of meaning in terms of international law.
The sovereignty issues surrounding the Diaoyutais have nothing to do with researching ancient documents; they involve international treaties.
Before the Treaty of Shimonoseki was signed in 1895, Japan had already incorporated the Diaoyutais into its territory. In terms of the territories handed over to Japan in this treaty, the latitude and longitude of the Pescadores Group were clearly stated, while, as far as Taiwan goes, it only specified “the island of Formosa, together with all islands appertaining or belonging to the said island of Formosa.”
Article 2, (b) of the Treaty of San Francisco states: “Japan renounces all right, title and claim to Formosa and the Pescadores.” It did not, however, list any other appertaining islands or any latitude and longitude and therefore this cannot be used to say that Japan gave up the Diaoyutai Islands.
Instead, for the Diaoyutais, the treaty stated that, “Japan will concur in any proposal of the United States to the United Nations to place under its trusteeship system, with the United States as the sole administering authority, Nansei Shoto south of 29 degrees north latitude (including the Ryukyu Islands and the Daito Islands), Nanpo Shoto south of Sofu Gan (including the Bonin Islands, Rosario Island and the Volcano Islands) and Parece Vela and Marcus Island.”
In 1953, the US civil administration of the Ryukyu Islands announced that the territory of the Ryukyus would include all islands, atolls and rocks between 28 degrees north latitude, 124 degrees 40 minutes east longitude and 240 degrees north latitude, 122 degrees east longitude.
In negotiations with the US in 1970, the then-Republic of China ambassador to the US, Chow Shu-kai (周書楷) admitted that this clearly defined latitude and longitude placed the Diaoyutais within the area under US trusteeship.
According to the Treaty of San Francisco, Japan did not renounce the Nansei Shoto and therefore the US admitted that Japan still has residual sovereignty over these areas.
In 1972 at the end of their entrustment, they were returned to Japan and the US merely stated that it did not hold any position on sovereignty disputes over the region before the Treaty of San Francisco was in existence.
However, before the Treaty of San Francisco, there were no disputes over the sovereignty of the Diaoyutai Islands.
To now rely on archaic Chinese documents to proclaim sovereignty over the Diaoyutais is as ludicrous as claiming that because Taiwan has temples devoted to the God of War, Guangong (關公), Guangong once ruled Taiwan.

When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
Japanese Prime Minister Sanae Takaichi on Monday announced that she would dissolve parliament on Friday. Although the snap election on Feb. 8 might appear to be a domestic affair, it would have real implications for Taiwan and regional security. Whether the Takaichi-led coalition can advance a stronger security policy lies in not just gaining enough seats in parliament to pass legislation, but also in a public mandate to push forward reforms to upgrade the Japanese military. As one of Taiwan’s closest neighbors, a boost in Japan’s defense capabilities would serve as a strong deterrent to China in acting unilaterally in the
Taiwan last week finally reached a trade agreement with the US, reducing tariffs on Taiwanese goods to 15 percent, without stacking them on existing levies, from the 20 percent rate announced by US President Donald Trump’s administration in August last year. Taiwan also became the first country to secure most-favored-nation treatment for semiconductor and related suppliers under Section 232 of the US Trade Expansion Act. In return, Taiwanese chipmakers, electronics manufacturing service providers and other technology companies would invest US$250 billion in the US, while the government would provide credit guarantees of up to US$250 billion to support Taiwanese firms
