The US is intensifying its efforts to combat the alleged transshipment of Chinese goods through Southeast Asian countries to avoid tariffs. This crackdown is causing concern in the region, as Southeast Asian economies could face increased scrutiny and potential trade disruptions.

This action raises questions about the future of trade relations and the potential impact on Southeast Asia's role in global supply chains.
