The Taiwan People’s Party has a two-year clause for its at-large seats in the Legislative Yuan, with eight legislators expected to resign in 2026. Among the nominees for a replacement is Li Zhenxiu (李貞秀), the Chinese spouse of a Taiwanese national. The question is whether she must give up her Chinese nationality.
This issue is simple in some ways and complex in others. The law clearly stipulates that individuals of foreign nationality cannot hold public office in Taiwan. So, according to the law, Li cannot hold public office. The issue becomes more complicated when considering this question: Are those holding People’s Republic of China (PRC) nationality considered foreign nationals? If so, how should one go about renouncing their PRC nationality?
One might argue that the preamble of the Additional Articles of the Constitution of the Republic of China (ROC) (中華民國憲法增修條文) states: “To meet the requisites of the nation prior to national unification,” while Article 1 of the Act Governing Relations Between the People of the Taiwan Area and the Mainland Area (臺灣地區與大陸地區人民關係條例) states: “This act is specially enacted for the purposes of ensuring the security and public welfare in the Taiwan Area ... before national unification.”
From these examples, it seems that those holding PRC nationality are not considered foreign nationals. However, these provisions present a false and unrealistic narrative — the reality is that some countries acknowledge that Taiwan — the ROC — is a country, while others acknowledge that the PRC is a country.
Many democratic states have indicated that UN Resolution 2758 does not involve Taiwan, and therefore does not preclude Taiwan from participating in international organizations. In other words, Taiwan and China are both countries — or, in the words of President William Lai (賴清德), they are not subordinate to each other.
The Nationality Act (國籍法) stipulates that “a national of the ROC who acquires the nationality of another country shall have no right to hold government offices of the ROC.”
Therefore, people must renounce their foreign nationality — Chinese included — if they hope to serve as a legislator. Article 3 of the Legislators’ Conduct Act (立法委員行為法) states that it is the responsibility of legislators to perform duties on behalf of nationals, and should therefore observe the Constitution and be loyal to the nation.
Additionally, according to Article 2 of the Oath Act (宣誓條), legislators are required to take the oath outlined in the act, including the content: “I do solemnly and sincerely swear that I will observe the Constitution, be loyal to the nation, and perform duties on behalf of nationals without playing favorites and committing irregularities, pursuing personal profits, taking bribes, or interfering in the judicial process. Should I break my oath, I shall be willing to submit myself to the severest punishment.”
To be loyal to the nation, however, could one really possess the nationality of another country? How can you truly be loyal as a foreign national?
It is entirely logical that legislators must first renounce foreign nationality before taking office.
However, if Li wants to renounce her PRC nationality, obtaining the necessary documents might prove difficult. Article 16 of the Chinese nationality law states: “Applications for ... renunciation of Chinese nationality are subject to examination and approval by the Ministry of Public Security of the People’s Republic of China. The Ministry of Public Security shall issue a certificate to any person whose application has been approved.”
In this situation, it is unlikely that the Chinese Ministry of Public Security would approve Li’s application and provide her with the documents to renounce her PRC nationality.
There might be a workaround: When Li takes her oath of office to become a legislator, she could publicly present a document indicating her intent to renounce her Chinese nationality. In fact, Article 9, Section 4 of the Nationality Act states: “A foreign national may be exempted from submitting a certificate of loss of original nationality if ... he/she cannot obtain a certificate of loss of original nationality for reasons not attributable to himself/herself.”
If she wishes to serve as a legislator, but does not renounce her Chinese nationality, the situation would become even more tangled.

The Chinese Communist Party (CCP) has long been expansionist and contemptuous of international law. Under Chinese President Xi Jinping (習近平), the CCP regime has become more despotic, coercive and punitive. As part of its strategy to annex Taiwan, Beijing has sought to erase the island democracy’s international identity by bribing countries to sever diplomatic ties with Taipei. One by one, China has peeled away Taiwan’s remaining diplomatic partners, leaving just 12 countries (mostly small developing states) and the Vatican recognizing Taiwan as a sovereign nation. Taiwan’s formal international space has shrunk dramatically. Yet even as Beijing has scored diplomatic successes, its overreach
After more than a year of review, the National Security Bureau on Monday said it has completed a sweeping declassification of political archives from the Martial Law period, transferring the full collection to the National Archives Administration under the National Development Council. The move marks another significant step in Taiwan’s long journey toward transitional justice. The newly opened files span the architecture of authoritarian control: internal security and loyalty investigations, intelligence and counterintelligence operations, exit and entry controls, overseas surveillance of Taiwan independence activists, and case materials related to sedition and rebellion charges. For academics of Taiwan’s White Terror era —
After 37 US lawmakers wrote to express concern over legislators’ stalling of critical budgets, Legislative Speaker Han Kuo-yu (韓國瑜) pledged to make the Executive Yuan’s proposed NT$1.25 trillion (US$39.7 billion) special defense budget a top priority for legislative review. On Tuesday, it was finally listed on the legislator’s plenary agenda for Friday next week. The special defense budget was proposed by President William Lai’s (賴清德) administration in November last year to enhance the nation’s defense capabilities against external threats from China. However, the legislature, dominated by the opposition Chinese Nationalist Party (KMT) and Taiwan People’s Party (TPP), repeatedly blocked its review. The
In her article in Foreign Affairs, “A Perfect Storm for Taiwan in 2026?,” Yun Sun (孫韻), director of the China program at the Stimson Center in Washington, said that the US has grown indifferent to Taiwan, contending that, since it has long been the fear of US intervention — and the Chinese People’s Liberation Army’s (PLA) inability to prevail against US forces — that has deterred China from using force against Taiwan, this perceived indifference from the US could lead China to conclude that a window of opportunity for a Taiwan invasion has opened this year. Most notably, she observes that
