Thailand has recommenced exporting durian to China, following a suspension due to the discovery of prohibited residues in the fruit. The Thai Ministry of Agriculture and Cooperatives has taken steps to address the issue, including sending a delegation to Beijing to discuss the matter with China's General Administration of Customs. Thailand has been allowed to resume exports if the durian has an additional O-yellow certificate from approved laboratories. The Thai Ministry has also urged durian producers to adhere to a '4 no' principle, prohibiting crushed shells, harmful organisms, misrepresentation of growing area codes, and banned substances. This comes after the discovery that some durian packaging factories in Thailand had illegally used substances containing O-yellow.
