Lai was originally scheduled to visit the Kingdom of Eswatini, Taiwan’s diplomatic ally in Africa, from April 22 to 27. Taiwan’s Central News Agency reported that Seychelles, Mauritius and Madagascar abruptly canceled flight permissions for the presidential aircraft, prompting Taiwan’s Presidential Office to pause the trip; the report attributed the disruption to Chinese interference.
After the delay, Lai still reached Eswatini on May 2, Taipei time, for a state visit. Taiwan’s Presidential Office said the trip was built around three themes — shared security, shared economic prosperity and shared digital prosperity — with the aim of deepening Taiwan–Eswatini ties.
For Beijing, the issue was not only Eswatini. The bigger concern was the image of Taiwan’s elected president traveling as a head of state to a country that maintains formal relations with Taipei. Ahead of the trip, China’s Taiwan Affairs Office said it firmly opposed any attempt internationally to create “two Chinas,” “one China, one Taiwan” or “Taiwan independence.”
Taiwan’s Foreign Ministry responded that Taiwan has the right to choose its own international exchanges and develop relations with other countries, and that it does not accept interference or suppression from any country. The ministry also said presidential visits follow international practice and are normal diplomatic activity.
That is the core divide: Taipei frames the visit as standard diplomacy with an ally, while Beijing views such appearances through its one-China position and treats them as politically unacceptable international visibility for Taiwan.
This might have remained a familiar cross-strait exchange of accusations if the obstacle had not involved flight permissions.
Taiwan’s Foreign Ministry said on April 24 that the US executive branch and Congress had expressed concern over the obstruction of Lai’s planned Eswatini trip and had urged China to stop pressuring Taiwan.
According to Taiwan’s Foreign Ministry, the US State Department said the relevant countries had acted at China’s direction and interfered with the safety and dignity of routine travel by Taiwan officials. Washington also stressed that countries responsible for flight information regions manage international airspace extending far beyond their own sovereign airspace, and that this responsibility exists to ensure aviation safety — not to serve as Beijing’s political tool.
In plain English, the US concern was not only whether Lai could travel. It was whether aviation-management systems designed for safety could be leveraged by a third party for political pressure. Taiwan’s Foreign Ministry said the US described the episode as another example of Beijing intimidating Taiwan and its global supporters, and of misusing the international civil aviation system.
US support rested on two main arguments.
First, Washington framed the trip as routine. The US State Department told Taiwan’s Central News Agency that Taiwan is a trusted and capable partner of the United States and many other countries, and that a Taiwan president’s visit to Eswatini should not be politicized.
The State Department also noted that every democratically elected Taiwan president has traveled abroad to visit Taiwan’s diplomatic allies. It pointed out that Lai’s predecessor, Tsai Ing-wen, visited Eswatini in both 2018 and 2023.
Second, the US placed the incident in the broader category of coercion. Taiwan’s Foreign Ministry said Washington urged Beijing to stop military, diplomatic and economic pressure against Taiwan and instead address differences through meaningful dialogue.
Eswatini’s significance is not just geographic. For Taiwan, it is a place where formal diplomatic ties and presidential-level diplomacy remain visible. Lai’s visit was presented by Taiwan’s Presidential Office as a way to deepen bilateral ties through security, economic and digital cooperation.
That is why the same trip could mean different things to different governments. For Taiwan, it was a continuation of normal relations with an ally. For Beijing, it was an international setting that could be read as validating Taiwan’s separate diplomatic presence. For Washington, the flight-permission dispute became a test of whether Beijing was using third countries and aviation procedures to pressure Taiwan.
The bottom line: Lai’s Eswatini visit became a China–US flashpoint because it combined Taiwan’s head-of-state diplomacy, Beijing’s one-China objections and US concern that flight-safety mechanisms were being politicized. What began as a bilateral visit between Taiwan and Eswatini was amplified into a dispute over international rules, diplomatic space and pressure tactics.
