CPTPP is an important high-standard free trade agreement in Asia-Pacifi c region. Since CPTPP starts the accession process, United Kingdom, China and other economies have formally requested accession. UK may become the fi rst new member of CPTPP. UK-Australia FTA, an agreement between UK and the member of CPTPP reached just before the CPTPP accession negotiation launched, has positive impact on UK’s accession process. The FTA shows that UK, as an independent economy, can achieve an agreement, which has much political signifi cance. Meanwhile, the agreement can improve UK’s receptiveness to CPTPP’s standards. When pushing the accession process of CPTPP, China need to solve two problems, which are the diffi culty of acquiring all CPTPP members’ consensus and meeting CPTPP’s standards. UK accelerates the negotiation of Mega-FTA by reaching bilateral agreements, which are the experience that China can learn to promote its CPTPP accession process. China need to strengthen the communication with CPTPP members, promote the development of highstandard free trade agreement network and continue the process of deepening reform as well as opening up. Meanwhile, China should prepare that it may be diffi cult for China to join CPTPP in the short run.
