BEIJING — A report Monday on Chinese manufacturing suggests that Beijing’s trade war with the U.S. is causing domestic economic damage.

Surveys of manufacturers across Asia for May showed that business confidence has been shaken by the conflict over President Donald Trump’s demands that Beijing change its industrial planning strategy and find other ways to redress huge trade surpluses.

But in a move that could ratchet back some tensions, the world’s largest association of technology professionals said it is lifting a research cooperation restriction it had imposed on employees of Chinese tech giant Huawei.
