Breaking News-RTRS-China soy, soyoil market stay strong, corn weak-survey

BEIJING, Nov 14 (Reuters) - China's soy and soyoil markets were expected to remain strong in the week ahead, although the outlook for soyoil weakened as supplies grew, while corn remained bearish on weak demand, according to a survey by an official think-tank. China's imports of soybeans remained robust even after the slide of domestic soy prices, but the price drop left domestic prices higher than imports, according to the survey by the official China National Grain and Oils Information Centre (CNGOIC).
