China is considering a maritime “quarantine strategy” to potentially isolate Taiwan amid escalating tensions in their maritime boundary, as reported by the Washington-based think tank Center for Strategic and International Studies (CSIS).

Outlined in a report published on June 5, this strategy would involve China’s coast guard and maritime militia imposing restrictions on Taiwan’s ports. The aim is to disrupt vital supplies without engaging in outright war, presenting it as a gray zone tactic rather than a full blockade.

The quarantine strategy seeks to exert pressure on Taiwan while avoiding direct military confrontation with the United States, which supports Taiwan’s defense. Experts caution that such actions could strain international relations and affect global trade, given Taiwan’s critical role in semiconductor production and its economic ties with China.

According to the CSIS report, the political and operational objectives of the quarantine are not to completely seal Taiwan off from the world, but to exert control over its maritime and air commerce. The report highlights that a quarantine could selectively target the delivery of specific goods, such as US weapons shipments to Taiwan, aiming to demonstrate China’s authority over Taiwan.

Beijing continues to assert its control over Taiwan, which it considers as its own territory despite never governing it. This move comes amidst heightened regional tensions, with Taiwan maintaining unofficial relations with major Western democracies. The sustainability of such a quarantine and its potential economic and political repercussions remain subjects of concern.

Critics argue that this strategy might push Taiwan towards declaring independence, a move that Beijing has threatened to oppose forcefully.
