After waging war on Canadian dairy, steel and aluminum, U.S. trade representatives are setting their sights on foreign berry farmers and vegetable growers.

The products include frozen pork, asthma and diabetes medications and some high-tech components.

Unlike many other central banks, the Bank of Canada has not moved to lower interest rates to support growth in response to global economic weakness.

Trade tensions between the U.S. and China have flared repeatedly after U.S. President Donald Trump imposed punitive tariffs last year.

U.S. President Donald Trump on Friday said he had told Chinese President Xi Jinping that crushing the Hong Kong protesters would have "a tremendous negative impact" on efforts to reach an accord to end a 16-month trade war.

Farmers have been hit hard by the trade war with China. Trump has been trying to assure them that they will come out ahead in the end.

The rules cover all meetings Chinese diplomats have with representatives of state, local and municipal governments and all visits to public and private educational and research institutions, including national laboratories in the U.S. and its territories.

The administration agreed to suspend a tariff hike on $250 billion worth of Chinese imports that was set to take effect Tuesday. And China agreed to buy up to $50 billion in U.S. farm products.

China's top official at the UN General Assembly, Foreign Minister Wang Yi, sat silently during Trump's remarks, showing no reaction on camera.

The Chinese Commerce Ministry gave no details but said the two sides want to create “favorable conditions.”
