Taiwan Strait moves $3 trillion trade

Taiwan said Tuesday it detected two Chinese warships near the Penghu islands and sent naval and air forces to monitor them. (msn.com) Taiwan’s defense ministry said the ships were operating about 24 nautical miles southwest of Penghu, an archipelago in the middle of the Taiwan Strait. Taipei said it responded with aircraft, navy vessels and coastal missile systems. (msn.com) Penghu sits between Taiwan and China on one of Asia’s busiest shipping lanes. The Center for Strategic and International Studies estimated that about $2.45 trillion in goods moved through the Taiwan Strait in 2022, or more than one-fifth of global maritime trade. (csis.org) That traffic includes cargo bound for Taiwan’s ports, Chinese ports and third countries using the route as a shortcut between Northeast Asia and Southeast Asia. CSIS estimated Taiwan’s ports alone handled about $586 billion in trade in 2022, including transshipments. (csis.org) Researchers at CSIS say Beijing has options short of invasion, including coast guard-led inspections or a quarantine that could disrupt shipping without an amphibious assault. They wrote that even limited interference could raise insurance costs, force rerouting and delay port calls in China and Taiwan.

CSIS said a ship avoiding the area entirely could add roughly 1,000 miles by sailing south of the Philippines and north through the Miyako Strait. (csis.org) Taiwan has been building its response around what it calls “gray zone” pressure, meaning coercive acts below the threshold of open war. In June 2025, President Lai Ching-te oversaw coast guard drills in Kaohsiung that simulated retaking a ferry, and said Taiwan faced “constant grey intrusion” from China. (investing.com) Lai’s government has also accused Beijing of squeezing Taiwan’s diplomatic space far from the strait. On April 21, Taiwan canceled Lai’s planned trip to Eswatini after saying China pressured Seychelles, Mauritius and Madagascar to revoke overflight permission; Madagascar said it denied the request under its one-China policy. (channelnewsasia.com) Beijing says Taiwan is part of China and rejects Lai as a separatist. Taipei says only Taiwan’s people can decide their future, and Tuesday’s Penghu deployment showed how quickly that political fight can spill into a commercial chokepoint.
