Thousands of containers of agricultural products, including cassava and cassava products, are experiencing congestion at border gates due to China's tight control to prevent Covid-19, affecting delivery progress. Despite this, the export of cassava and cassava products is expected to be active again by the end of 2021, with high export prices. In the first 10 months of 2021, Vietnam exported 1.59 million tons of tapioca starch, valued at $747.33 million, a decrease in volume but increase in value over the same period in 2020. The export of dried cassava chips also saw a significant increase due to a sharp increase in world corn prices, with China increasing imports of cassava chips to make animal feed. However, Vietnam's market share of cassava products in China has decreased compared to 2020 while Thailand's market share has increased, indicating that Vietnam's cassava products are facing strong competition in the Chinese market.
