CHINA, Mexico and Canada hit back today at the decision by US President Donald Trump to raise tariffs on their products.

China responded to the 20 per cent across-the-board US tariffs by announcing it will impose its own additional tariffs of up to 15 per cent on imports of key US farm products, including chicken, pork, soy and beef, and expanded controls on doing business with key US companies.

Mexico said that it would announce its retaliation to the 25 per cent tariffs, imposed by the US, in a speech next Sunday.
