China has suspended imports from two Quebec-based pork producers, Olymel and Drummond. The move is seen as a sign that diplomatic tensions between China and Ottawa could be affecting a wider swath of Canada’s food exports. The timing of this move is unusual as China is facing a significant shortage of pork due to the outbreak of the African swine fever that could see up to 200 million pigs lost to disease or slaughter. Many are watching if China will remove or reduce its 70 percent tariff on US pork imports. China is the biggest buyer of Canadian canola, and the second-biggest buyer of Canadian pork.
