(BBC News) Asian shares slid on Monday morning after US President Donald Trump followed through on his promise to impose tariffs on Canada, Mexico and China.
Investors are bracing for a potential trade war that could hit the earnings of major companies and dent global growth.
Canada and Mexico have said that they will hit back with retaliatory tariffs while China promised “corresponding countermeasures” and vowed to challenge Trump’s move at the World Trade Organization.
Trump has said the tariffs are necessary to halt the flow of illegal drugs and immigration into the US.
Hong Kong’s Hang Seng Index was down 0.7%, Japan’s Nikkei 225 was 2.8% lower, South Korea’s Kospi tumbled 3% and Australia’s ASX 200 fell 1.9%.
Markets in mainland China remained closed for the Lunar New Year holiday.
Meanwhile, the US dollar was showing strength, rising to a record high against China’s yuan, while the Canadian dollar plunged to its lowest level since 2003.
“The prospect of having a long and protracted trade spat between the world’s two biggest economies is causing investors to take risk off the table today,” said Tim Waterer, chief market analyst at financial services firm KCM Trade.
“The other worry for investors is which countries may be on Trump’s tariff hit list next.”
