SHANGHAI, April 7 (Reuters) - Hong Kong and Chinese

stocks dived on Monday as markets around the world crumbled in

the face of a widening global trade war and fears it will

unleash a deep recession.

Hong Kong's Hang Seng index was down 8% in early

trade. Shares in online giants Alibaba ( BABA ) and Tencent ( TCTZF )

were down more than 8%.

China's CSI300 blue-chip index fell 4.5%.

China, which is now facing U.S. tariffs of over 50%,

responded in kind on Friday by slapping extra levies on U.S.

imports.
