China typically buys from the United States in the last quarter and first couple of months of the year, when the US harvest dominates the market. But Chinese buyers have steered clear of US produce amid the tit-for-tat trade dispute and scooped up Brazilian beans instead.
Chinese imports of the oilseed from America, its second largest supplier, fell sharply last year and ground to a virtual halt in November. Limited buying resumed after the two countries agreed to a truce on Dec. 1.
However, China brought in 4.93 million tonnes of Brazilian soyabeans in January, more than doubling last year's 2.07 million tonnes.
Stockpiling means Chinese crushers have sufficient stocks on hand at present, a situation set to continue in coming months, analysts said, as the new Brazilian crop reaches the market.
China crushes soyabeans to produce soyameal which is fed to its massive livestock herds but an ongoing African swine fever epidemic in China has also dampened demand for feed.
Top negotiators from Beijing and Washington last week discussed a set of agreements aimed at ending the trade war, including a 10-item list to alleviate trade imbalances, with additional Chinese purchases of US agricultural products.
China committed to buy an additional 10 million tonnes of US soyabeans, US Agriculture Secretary Sonny Perdue said on Twitter on Friday. President Donald Trump said on Sunday he would delay an increase in US tariffs on Chinese goods scheduled for later this week thanks to progress in trade talks.
