Some people raised the issue of fair trade. As a matter of fact, free trade is the premise of fair trade. Restricting free trade will not make trade fairer.

Attempting to impose unilateral rules or making fair trade a political issue will not lead anywhere.

They were also asked to strengthen their awareness of the law and patriotism to boost the country's innovation-driven growth and repay society.
