China has never rejected experts of the World Health Organization from visiting laboratories in Wuhan, Hubei province, during their visits in the city, a health official said on Friday.

China has made steady progress in deleveraging, and the country's leverage ratio has been gradually lowered.

China continued to send more students than any other country, followed by India, South Korea and Saudi Arabia. But booming years of growth from China have leveled off.

China has introduced a raft of opening-up policies in the banking and insurance sectors over the last two years, including expanding the business scope of foreign-invested firms and easing market access.
