Vietnam's government has stopped seeking the National Assembly's ratification of the US-led Trans-Pacific Partnership (TPP) pact, as conditions are not sufficient following changes in the United States, the country's prime minister said on Thursday. 'The United States has announced it suspends the submission of TPP to the parliament so there are not sufficient conditions for Vietnam to submit its proposal for ratification,' Prime Minister Nguyen Xuan Phuc told the National Assembly.
