More than 3 billion yuan has been spent on the Fangshan Global Geopark by the district government ahead of a mid term review by UNESCO over the park's future.

As part of its efforts to pass the review, the Fangshan district government is also relocating hundreds of thousands of people as well as closing coal mines - all before the July 31 deadline.

The 950 sq km park was recognized by UNESCO as a global geopark in September 2006 - the only place in Beijing to get the honor.
