China's state-owned grain trader, Sinograin Corp, has purchased nearly 500,000 metric tons of U.S. soybeans for shipment in March and April, despite Brazilian beans being cheaper. The purchases follow a similar pattern last week, where China booked deals for about 750,000 tons for January-March shipment. These purchases come as China's overall agricultural imports have slowed down and Brazil is preparing to harvest a record crop, leading to concerns about low processing margins and potential tariffs from the U.S. Under the Trump administration. The motives behind Sinograin's decision to pay more for U.S. soybeans despite the higher cost are not clear, but it could be seen as an effort to build up China's strategic reserves or a gesture to the new U.S. administration.
