Since 2002 TRL since have begun a number of valuable collaborations with tree-ring labs in China in the pursuit of reconstructing the South East Monsoon. China is a very large and diverse country, both ecologically and culturally. Consequently, travelling across the country is an amazing experience and really gives one an appreciation of just how large China is. Because of China's extreme topography, it's scale, and its location in Asia, China is one of the most important countries in the TRL Asian Monsoon Project. .
