In a significant escalation of trade tensions, China has announced retaliatory measures against the United States’ newly imposed port fees. The Chinese Commerce Ministry revealed on Tuesday that it would levy a special port-entry charge of 400 yuan ($56) per net ton on US-linked container ships. This rate is set to increase annually, reaching 1,120 yuan by April 17, 2028. Additionally, China has sanctioned five US-related subsidiaries of South Korea’s Hanwha Ocean, accusing them of aiding US investigations into China’s maritime and shipbuilding sectors, which Beijing claims undermines its sovereignty and development interests. The sanctions prohibit Chinese entities from engaging in transactions or cooperation with the listed firms. A spokesperson for the Chinese Commerce Ministry emphasized that while China is open to dialogue, it is prepared to defend its interests if necessary. The spokesperson also criticized the US for its approach, stating that negotiations should not be conducted under threats or intimidation. This development comes ahead of a potential meeting between Chinese President Xi Jinping and US President Donald Trump at the APEC Summit in Seoul later this month. The US had previously imposed fees on Chinese ships entering its ports, citing unfair trade practices. China’s new measures are seen as a direct response to these actions, further straining bilateral relations. The situation underscores the growing rivalry between the two nations in the global trade and maritime sectors, with both sides taking increasingly assertive stances to protect their economic interests.
