The Ministry of Industry and Trade said implementing the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) over past five years has helped expand markets, attract investment, and bring competitive advantages to exports, but has also put Vietnamese businesses at risk of being investigated and subject to trade defense measures. The use of trade defense tools is increasing in CPTPP member countries. Related investigations are not only more numerous but also more complex in scale and diverse in products affected. This poses many challenges for Vietnamese exporters, especially in the context of the CPTPP gradually entering into a new phase of implementation.
