HONG KONG, June 7 (Reuters) -

China's blue-chip stocks dropped on Wednesday as investor sentiment was hit by worse-than-expected May export data, while Hong Kong tech stocks jumped, encouraged by U.S. Secretary of State Antony Blinken's plan to visit China in the coming weeks.

** China's blue-chip CSI 300 Index fell 0.36%, while the Shanghai Composite Index were flat.

** Hong Kong's Hang Seng Index rose 0.97%, and the Hang Seng China Enterprises Index gained 1.01%.

** Imports fell by 4.5%, compared with a 7.9% decline in April.

** Blinken will travel to China in the next few weeks, an official said on Tuesday.

** The visit is intended by Washington to be a major step toward what President Joe Biden has called a "thaw" in relations between the world's two largest economies.
