台湾目前只剩12个外交盟友，主要在太平洋和拉丁美洲；尽管规模不大，埃斯瓦蒂尼仍是台湾在非洲唯一的邦交国。与公海不同，FIR（飞行情报区）由具体航空当局管理，可决定是否准许外国飞机进出，因此被拒绝并不必然构成国际法违例。2026年的事件是中国首次公开成功阻止台湾总统访问其盟友；此前2002年陈水扁赴印尼和2007年在返台途中遭遇墨西哥FIR限制，主要是改道而非同等政治后果。
这种做法与更广泛的地缘战略“ choke point ”控制同步：伊朗在霍尔木兹海峡压制约五分之一全球石油供给，而美国在同一航道采取封锁，应对举措同样使航行自由规则受压。台湾担心该模式会复制到其他地区，内陆国家巴拉圭也被视作潜在脆弱点，因为其周边国家更偏向与北京交往。特朗普时期部分西方协调力削弱，加之中国对未承认台湾的塞舌尔、马达加斯加和毛里求斯的援助影响力增强，且台湾多次指控存在债务减免、融资与制裁压力，使“空中围堵”被制度化的风险上升。
For years, Xi Jinping has maintained pressure on Taiwan by restricting its leaders’ diplomatic meetings and participation in global institutions, and that pressure has now extended into airspace. In March 2026, Seychelles, Mauritius, and Madagascar revoked overflight clearance for President Lai Ching-te’s trip to Eswatini in a coordinated final-hour sequence, which forced a cancellation, and Taiwan officials said it was arranged at China’s request. The restriction affected a broad corridor of regional skies, not just one airport.
Taiwan now has only 12 diplomatic partners, mostly in the Pacific and Latin America, and Eswatini—though small—remains Taiwan’s only African ally. Unlike the high seas, a Flight Information Region (FIR) is managed by a specific air-traffic authority that can permit or deny transit, so the denials are hard to frame as clear international-law violations. The 2026 episode was the first known instance of China successfully stopping a Taiwanese president from visiting an allied state; earlier cases involving Chen Shui-bian in 2002 (Indonesia) and 2007 (Mexico) caused rerouting, not the same level of political disruption.
The move fits a wider trend of geopolitical control of transit chokepoints: Iran is suppressing roughly one-fifth of global oil flow through the Strait of Hormuz, while U.S. policy has also used blockades there, and both dynamics strain norms of free navigation. Taiwan fears replication elsewhere, with landlocked Paraguay viewed as a vulnerability because neighboring states lean toward Beijing. In the Trump-era environment of reduced Western coordination, combined with China’s aid leverage over Seychelles, Madagascar, and Mauritius (none recognize Taiwan diplomatically) and Taiwan’s claims of debt-relief and finance pressure, the precedent of aerial containment appears increasingly repeatable.
