Hong Kong will file a complaint on recent US tariffs imposed on the city to the World Trade Organization, claiming the US has completely ignored the city's status as a separate customs territory, chief secretary Eric Chan said on Tuesday.

The US's imposition of a 25% tax on imported steel and aluminum is expected to have a significant impact on domestic and foreign businesses, including those that do not directly produce or export these two products.

In the context of significant changes in the global seafood market, the US seafood sector is impacted by political factors, tariffs, and consumer demand.

US President Donald Trump substantially raised tariffs on steel and aluminium imports on Monday to a flat 25% "without exceptions or exemptions" in a move he hopes will aid the struggling industries in the US but which also risks sparking a multi-front trade war.

US tariffs on steel and aluminium imports are expected to lead a surge of products into Malaysia, a local trade group warned on Wednesday and urged the government to step up its anti-dumping efforts.

US President Donald Trump said on Sunday that he will announce on Monday new 25% tariffs on all steel and aluminum imports into the US, which would come on top of existing metals duties in another major escalation of his trade policy overhaul.

President Donald Trump said on Friday he plans to announce reciprocal tariffs on many countries by Monday or Tuesday of next week, a major escalation of his offensive to tear up and reshape global trade relationships in the US' favour.

Canada will keep trying to persuade the Trump administration to drop its tariff plans, in part by reaching out to US states that have significant trading relationships with their northern neighbour, trade minister Mary Ng said.

President Donald Trump policies on imposing high import tariffs on China and other countries such as Canada and Mexico will give benefits for Indonesia, an expert said.

The Ministry of Industry and Trade (MoIT) has drafted scenarios in response to a possible global trade war following the Prime Minister’s recent warnings.
