China has already implemented the three-child policy. It was officially announced on May 31, 2021, during a meeting of the Politburo of the Chinese Communist Party, chaired by Xi Jinping. This move came in response to the country's declining birth rates and aging population, as revealed by the 2020 national census.
The policy was formally adopted in June 2021, and by August 2021, the Standing Committee of the National People's Congress amended the Population and Family Planning Law to allow each couple to have up to three children. This amendment also removed previous penalties for exceeding birth limits.
