According to merchants, ships carrying more than 700,000 tonnes of soybeans are at anchor off the coast awaiting to be unloaded.
According to experts, the prolonged stay of consignments had an impact on the rise in soybean meal prices in recent weeks. This makes nervous Brazilian and US exporters.
Traders say that the main reason for the delays is the heavy customs checks and unsufficient number of port warehouses.
In China, 9.59 million tonnes of soybeans were delivered in May, and 9 million tonnes in June. Stocks of soybean in Chinese ports are 7 million tonnes.
