The broader Chinese stock market has declined for much of 2023 after the economy did not rebound as much as many expected.

Chinese authorities are planning to cut the stamp duty on domestic stock trading by as much as 50%, three people with knowledge with the matter said, in a further attempt to revitalize the country's struggling stock market.

Chinese regulators including the Ministry of Finance, under the guidance of the State Council, submitted a draft proposal to the cabinet earlier this month, said two of the people, adding a decision could be made and announced as soon as Friday.
