--FILE--View of imported soybeans in Nantong city, east Chinas Jiangsu province, 23 September 2018. China is expected to enlarge its soybean planting area this year to cope with the potentially higher tariffs caused by trade frictions with the US. Prices are likely to compete with imported produce, according to the agriculture ministry. As the area expands, the supply of domestic soybeans will increase steadily, Tang Wei, a market chief at the Ministry of Agriculture and Rural Affairs said at a press conference today. "The next few months will be a key planting period for the main soybean producing areas in northeastern China, " Tang said. The ministry will track domestic and international production and market changes closely, release timely information about prices and demand, and offer policy support to guide market expectations.
