Vietnam

EP267 踏访湄公河：雨季、婚飞蚁与水利帝国 adds Vietnam’s 湄公河三角洲 branch. The source treats the delta as one of Vietnam’s major population and production regions, shaped by Vietnamese southward expansion, Chinese settler involvement, French colonial canal building, rice agriculture, and current saltwater-intrusion vulnerability.

Vietnam appears in vol.123.特朗普的“对等”关税案：不止是一场大型服从性测试 as the concrete example for Reciprocal Tariff Formula. The episode says the tariff calculation uses Vietnam’s goods-trade surplus with the United States relative to exports to the U.S. market, rather than simply matching Vietnam’s formal tariff rate on American goods.

In the source’s strategic reading, Vietnam is also one of the countries likely to face a hard Tariff Compliance Test because export dependence on the U.S. market gives Washington leverage. The country matters to China as well because East and Southeast Asian transshipment chains can transmit tariff pressure back into Chinese export production even when goods do not travel directly from China to the United States.
