China has blocked a fifth cargo of U.S. corn since mid-Nov¬≠ember after testing found a strain of genetically-modified (GMO) corn not yet approved for import. Three more cargoes may also be refused.

A cargo of 59,100 tons was turned away last week in the eastern Chinese province of Zhejiang after quarantine officials found MIR 162 — an insect-resistant GMO strain that the country’s agriculture ministry has yet to approve, Reuters cited an official as saying.

China, the world’s second largest corn consumer, has refused 180,000 tons of grain since mid-November. Observers believe it has less to do with the corn and more to do with other trade quarrels between the two countries.
