LONDON (Reuters) - World stocks were dragged lower on Wednesday by growing anxiety ahead of Washington's end of week deadline to impose tariffs on Chinese imports, while the yuan rebounded after China's central bank moved to calm investors.
The MSCI All-Country World index (MIWD00000PUS), which tracks shares in 47 countries, was down 0.1 percent on the day.
Washington has said it would implement tariffs on $34 billion of Chinese imports on July 6, and Beijing has vowed to retaliate in kind on the same day.
Concerns about the outbreak of a global trade war have, among other factors, prevented a sustained recovery in global stock markets since a violent selloff in February.

"So it could have a drag, and it will have a drag. But will it push the global economy into recession? Not yet."
