Wang Jiewen, vice minister of China's Ministry of Commerce, said at a press conference on Wednesday that China has been in informal contact with some member countries to join the Trans-Pacific Strategic Economic Partnership (TPP). He has indicated that he plans to expand his contacts to other member countries, and is actively carrying out preparatory work for joining the TPP.

Wang stressed that the purpose of the informal contacts is to "exchange technical views on relevant issues and to have a more accurate understanding and grasp of the content". At the same time, Wang said, China is studying and analyzing all the provisions of the TPP, which is seen as a hurdle for China to join because of its high level of tariff elimination and common rules, and it is believed to be working internally on the conditions for such membership.

The TPP was first announced by President Xi Jinping in November last year, when he said he would actively consider joining. At the same time, 15 countries, including Japan, China and South Korea, signed the Regional Comprehensive Economic Partnership (RCEP), demonstrating China's active involvement in the economic and trade framework in Asia. It has been pointed out that China's intention is to break the "siege" against China promoted by the United States.
