July 22 (Reuters) - The U.S. Senate Commerce Committee is set to consider bipartisan legislation to toughen a U.S. government ​ban on Chinese automakers entering the American market but some provisions remain under debate ahead of an expected vote Wednesday.

Republican Senator Bernie Moreno ‌of Ohio and Democratic Senator Elissa Slotkin of Michigan proposed legislation in April to codify a regulation imposed by the Biden administration that effectively bans all Chinese automakers from selling passenger vehicles ​in the U.S. and takes other steps to prevent China from entering ​the U.S. light-duty market. The bill would prohibit vehicle sales by automakers that are more than 15% owned by Chinese entities, which would apply to Mercedes-Benz MBGn.DE, which has nearly 20% Chinese ownership. Mercedes-Benz is lobbying to change the provision, U.S. lawmakers say.
