[BradleyLee]

China will implement the National VI emission standards nationwide in 2023. Here are the relevant details: 1. Timeline: The implementation of the National VI standards will be divided into two phases: "National VI a" and "National VI b", with corresponding effective dates of July 1, 2020, and July 1, 2023, respectively. In fact, National VI a is only a transitional phase from National V to National VI, and the full implementation of the National VI emission standards will take place in 2023. 2. Notes: Some models listed as compliant with the National VI emission standards are already on the market, newly launched, or about to be launched. Among them, the already available models are those currently on sale in the market that meet National VI standards, while newly launched models may not yet be widely available for purchase. Upcoming models refer to those that will soon be released in compliance with the emission standards. The implementation of National VI standards for heavy-duty trucks and medium/light-duty trucks is progressing in an orderly manner, with annual penetration rates gradually increasing. According to policy requirements, relevant models will fully transition to National VI B by 2023.
