China announced tariffs on over $2.6 billion worth of Canadian agricultural and food products on Saturday, retaliating against levies Ottawa introduced in October and opening a new front in a trade war largely driven by US President Donald Trump’s tariff threats. The levies, announced by the commerce ministry and scheduled to take effect on March 20, match the 100% and 25% import duties Canada slapped on China-made electric vehicles and steel and aluminium products just over four months ago.
