Five Chinese state-owned firms announced on Friday that they are delisting from the New York Stock Exchange, citing tougher US regulations.

They include PetroChina, Sinopec and China Life Insurance. All are on a list of Chinese entities that have been warned of possible delisting, should they fail to fully show their auditing records to US regulators.

Private companies on the list include online retail giant Alibaba Group Holdings.

Beijing is also strengthening oversight of Chinese firms whose stocks are traded abroad. Authorities suggested on Friday that they do not believe the decision by the five entities will affect the overseas listings of others.

Analysts say the regulations could further decouple the US and Chinese economies.
