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 0.49%, while the Shanghai Composite Index edged up 0.08%.

** 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.
