US-China trade tensions back as port fees take effect
開徵港口費讓中美貿易再度緊張
The US and China started charging new port fees on each other's ships on Tuesday, as trade tensions between the world's two biggest economies increase.
中美開始自本周二互相對彼此船隻徵收港口費，使全球兩個最大經濟體間貿易再度緊張。
China says its levies aim to safeguard the country's shipping industry from "discriminatory" measures and apply to US-owned, operated, built, or flagged vessels but not Chinese-built ships.
中方說明徵收費用的目的是保護國內船舶產業避免被歧視，對象是美方擁有、經營、建造、或為國籍船之船舶，但不包括中國建造者。
Beijing announced the levies last week alongside moves to tighten controls on its rare earth exports. US President Donald Trump responded with a threat of an additional 100% tariff on China.
北京上週發布收費及更嚴苛之稀土出口管制等措施。美國總統回應，威脅將對中國徵收100%之額外關稅。
Also on Tuesday, new US tariffs came into effect on imported timber, kitchen cabinets and upholstered furniture, much of which comes from China.
另外在週二，美國針對進口之木材、櫥櫃和軟墊家具新關稅政策開始生效，此類貨物大部分源自中國。
Chinese state media said the US duties on Chinese ships violated a maritime transport agreement between the two countries. In retaliation, US-linked ships berthing at Chinese ports are now charged 400 yuan (£42; $56) per net tonne. The duties are closely matched to the port fees imposed by Washington. They will also apply to ships operated by US firms, and those in which an American company holds a stake of 25% or more. The fees will rise each year, reaching 1,120 yuan per tonne in April of 2028, state broadcaster CCTV said.
中國媒體稱美國對於中國船舶收費一舉，違反兩國海事運送協定，並對於停靠中國港口之美國船舶收取每淨噸400元人民幣，作為反制。
該費用與華盛頓徵收之港口費相當接近。中國亦將此政策用於美國及其持股高於25%之企業。CCTV稱該費用將逐年增加，至2028年將高達每公噸1,120人民幣。
Ships carrying dry bulk cargoes like coal and other raw materials could have to pay up to $3m in port fees from today, said freight analyst Claire Chong.
By 2028, some the biggest vessels that carry nearly 200,000 tonnes in dry bulk could have to pay more than $10m in fees, she estimates.
根據運費分析師預測，裝載煤礦等乾散貨物及其他原物料之船舶自今日起將被徵收高達3百萬之港口費。到2028年，裝載近20萬公噸之最大乾散貨船必須支付超過100萬的港口費。
