Since the Covid-19 outbreak, the cost of tomato production in Chinese producing areas has risen, leading to an increase in the export price of tomato paste. Strong heat waves in Europe have resulted in a surge in China's tomato paste exports. The Shadong Shagzhuo company buys tomatoes from the domestic market and sells the tomato paste in the export market. The price of tomato paste from Tianjin to Rotterdam is approximately US$ 1,150. The company attributes this increase in demand to a decrease in European tomato production volume and higher production costs due to the conflict between Russia and Ukraine.
