Steep American tariffs on Chinese goods worth tens of billions of dollars are due to take effect when the clock strikes twelve on Thursday night, as US President Donald Trump fires the first salvo in a trade war between the world's top two economies.
As much as US$20 billion of $34 billion Chinese goods on which United States will implement a 25-per-cent tariff beginning Friday are produced by foreign companies, including American companies, China's Commerce Ministry spokesman Gao Feng said at a regular press conference in Beijing.
Asked whether US companies would be targeted with "qualitative measures" in China in a trade war, Gao said the government would protect the legal rights of all foreign companies in the country.
"On the US's so-called list of $34 billion in taxable products, about $20 billion or 59 percent of them, are made by foreign invested enterprises, with American companies representing a significant portion", said Gao.
"US measures are essentially attacking global supply and value chains".
China rejected "threats and blackmail" ahead of planned US tariff hike, striking a defiant stance Thursday in a dispute companies worry could flare into a full-blown trade war and chill the global economy.
"China will not bow in the face of threats and blackmail", added Mr Gao.
Mercedes-maker Daimler, and BMW Porsche and Volkswagen raced up as much as 5 per cent after a newspaper report about a usa offer to suspend tariff threats on EU-made cars if the bloc lifts its duties on us ones.
The overnight slide in Asian markets, in particular Chinese shares which are now deep into "bear" market territory, highlighted the ongoing angst over U.S. President Donald Trump's trade tariff plans.
