Everybody knows that Chinese importers are extremely careful with fruit imported from Vietnam ever since Vietnamese fruit farmers struggled with food safety issues. China implemented strict border inspection of Vietnamese agricultural products in May, 2019. The border inspections are there to filter out the agricultural products that violate food safety standards. Vietnam exported a total of 2.2 million tons of fruit to China in the first 7 months of 2019, which is a decline of 68% compared to the previous year.
Vietnam currently has no way to expand export to the Chinese market, but some Vietnamese traders may have found another way into China. They are "hijacking" Cambodian fruit exports to China. Vietnamese companies establish banana plantations in Cambodia. This is without a doubt in response to the Chinese import restrictions on Vietnamese fruit.
Cambodia and China signed an agreement in August last year that allowed Cambodia to export bananas to the Chinese market. In the past, Cambodian companies opened plantations in Vietnam to "hijack" Vietnamese fruit export to the Chinese market, but now the tables have turned. Cambodia immediately took full advantage of the trade agreement. China is now the largest trade partner of Cambodia.
