The CPTPP is a high-quality, comprehensive FTA that aims to support sustainable and inclusive economic development and is open to others to join providing they meet the Agreement’s high standards.
New members applying to join the CPTPP will need to comply with the existing CPTPP Agreement. This means the text of the Agreement will not change. Current rules and obligations, as well as the exceptions that apply in the existing CPTPP Agreement, will not change.
The focus of negotiations with prospective new members will be on ensuring that the commitments they make on access for goods, services, investment, government procurement and temporary entry for businesspersons meet the high standards agreed by existing CPTPP members.
