BEIJING — China is poised to approve a sweeping rewrite of the country’s laws on foreign investment that it hopes will help pacify the United States and ease a rancorous trade dispute. The new rules would respond to some concerns among foreign governments and businesses but disregard many other worries.

China has been locked in a bruising struggle with the United States over the Trump administration’s contentions that Beijing has repeatedly forced foreign companies to hand over technological secrets as a condition of doing business in China, and has failed to protect American companies’ products from counterfeiting and other illegal copying. Beijing has denied any shortcomings in its existing practices, and the new law does call for tighter enforcement.

But the new law is made up of many single-sentence pronouncements on complex issues, with no details on how those rules would be carried out.

“This is good, but it’s not enough,” said Carlo Diego D’Andrea, the chairman of the European Chamber of Commerce in China.
