China's soybean imports from the United States plunged to zero in November, marking the first time since the trade war between the world's two largest economies started that China, the world's largest soybean buyer, has imported no U.S. supplies.

Instead, China has leaned on Brazilian imports to replace the U.S. cargoes, customs data showed on Monday.

China brought in 5.07 million tonnes of soybeans from Brazil in November, up more than 80 percent from 2.76 million tonnes a year ago, data from the General Administration of Customs showed.

Meanwhile, U.S. imports plunged from 4.7 million metric tons in November 2017 and were down from 67,000 metric tons in October.
