WASHINGTON (AFP) - A full-blown US-China trade war looms after President Donald Trump threatened tariffs on another US$200 billion (S$271.56) worth of Chinese goods, prompting Beijing to denounce his "blackmail" and warn of retaliation in kind.
The new tensions between the world's two largest economies come as Mr Trump, pursuing his "America First" agenda, also wages trade offensives against the European Union, Canada and Mexico, among others.
Here is a summary of Trump's trade conflicts:
After last week announcing new tariffs of 25 per cent against US$50 billion in Chinese imports, Mr Trump on Monday ordered his foreign trade chief to identify another US$200 billion worth of imports for a 10 per cent levy, citing China's "unacceptable" move to raise its own tariffs.
And if China makes good on its pledge to up its own retaliation, Mr Trump said he would hit a further US$200 billion of Chinese imports.
China, also affected by US steel tariffs, denounced Mr Trump's approach of "extreme pressure and blackmail" and warned it would "take strong, powerful countermeasures" if the President enacts his threats.
Tensions were also stoked by the US Senate's decision on Monday to reimpose a seven-year ban on sales of US high-tech chips to Chinese telecom firm ZTE, which had narrowly escaped collapse under a compromise deal announced by the Trump administration.
EU countries last Thursday approved a raft of tit-for-tat tariffs on up to 2.8 billion euros (S$4.39 billion) worth of US goods, including emblematic exports like jeans, whisky and motorcycles.
The reprisal came after Mr Trump on June 1 followed through on his threat to impose 25 per cent tariffs on steel imports and 10 per cent on aluminium imports from the EU.
Europe is also worried that Washington will follow up on a threat to impose punitive levies on imported cars, something particularly feared by the powerful German car industry.
CANADA AND MEXICO
Canada and Mexico, both members with Washington of the North American Free Trade Agreement (Nafta), have not been spared the US offensive on steel and aluminium and are threatening their own reprisals.
Mr Trump and Canadian Prime Minister Justin Trudeau traded barbs over the steel tariffs at a farcical summit of the G-7 richest countries that ended on June 9.
Meanwhile, talks among the three Nafta signatories, launched after Mr Trump demanded an overhaul of the "terrible deal", have snagged, notably owing to US demands to increase American content installed in duty-free Nafta vehicles.
Japan is another target of Mr Trump's steel tariffs, which Tokyo calls "extremely deplorable".
It has informed the World Trade Organisation (WTO) that it plans to impose retaliatory measures on US goods to the tune of 50 billion yen (S$618.04), after failing to persuade Washington to exempt it from the tariffs.
In March, Washington and Seoul announced agreement on a renegotiated free trade accord, giving US car-makers greater access to the South Korean market.
Mr Trump argued the original deal from 2012 was lopsided in Seoul's favour, but has also clouded the issue by appearing to link trade concessions to progress in his separate track of talks with nuclear-armed North Korea.
Russia, also hit by the US steel tariffs, has informed the WTO that it is planning its own retaliation.
Trade relations were already strained by US sanctions targeting oligarchs and businesses accused of supporting President Vladimir Putin's alleged efforts to undermine Western democracies.
Mr Trump announced in May he was abandoning the 2015 nuclear deal with Iran - which will mean new sanctions on the Islamic republic and punitive measures for those who trade with it.
Several companies - including Total and Peugeot of France, and Russia's Lukoil - have said they are preparing to exit Iran before US deadlines, the last of which is Nov 4.
