China will suspend pork imports from Canada's Frigo Royal after traces of a banned feed additive were found in its shipments, state media said Tuesday, amid a diplomatic row between Ottawa and Beijing. In a move seen as retaliation, Chinese authorities have detained two Canadian nationals -- a former diplomat and a business consultant -- on suspicion of endangering national security, and sentenced two others to death for drug trafficking. China has also blocked canola shipments from two major Canadian producers earlier this year, citing fear of pathogens.
