Chinese container shipping companies are bracing for a fresh financial hit as President Donald Trump’s administration begins imposing new US port fees on vessels linked to China, further deepening the ongoing trade war and adding strain to already declining freight markets. Cosco Shipping Holdings Co. and Orient Overseas International Ltd. (OOIL) will be the biggest casualties of the US Trade Representative’s policy taking effect Tuesday. Analysts at HSBC and Citigroup estimate that Cosco could face an additional $1.5 billion to $2.1 billion in fees in 2026, while OOIL may incur as much as $654 million.
