China imported no soybeans from the U.S. for a second straight month in October even as total imports surged to a record high on purchases from South America, with buyers aiming to avert supply disruptions amid trade tensions with Washington.

Data from China’s General Administration of Customs on Thursday showed U.S. soybean imports in October fell to zero from 541,434 metric tons a year earlier.

The decline followed China’s imposition of high tariffs on U.S. soybeans earlier in the year and the depletion of previously harvested U.S. supplies, or old-crop beans. China is the world’s biggest soybean importer.
