Under this program, technical resources, financial supports and information exchange were provided to the Chinese government and other coal industrial stakeholders. International anizations such as the UNDP and the GEF helped the Chinese in coalmine bed methane drainage. The first coal bed methane surface predrainage and underground directional drilling demonstration project was financed by the UNDP/GEF and hosted by Kailuan, Songzao and Tiefa coalmines (Raymond, 2021). The Chinese coalmine operators imported some technologies and equipment for coalmine methane monitoring and testing in coalmines, and began to build up resource data for coalmine methane. Magnitude of coal methane resources was recognized by international experts. In this period, no important national government policies to facilitate CMM capture and utilization were found. Rather, the international munities in CMM capture and utilization brought positive impacts on the Chinese government to change its opinions on the CMMrelated issues. The third period, 1996–2021, became the Chinese era of coalbed and coalmine methane recover and utilization. A number of significant changes have been perceived in this period. First, the national government changed its attitude, and methane was no longer simply a nuisance to mining, but an important potential clean energy resource. Second, experience with coalbed and coalmine methane recovery and utilization in OECD countries became relevant. Exploration of large license blocks by major foreign oil and gas panies began. Third, the Chinese published its forecasts of coalbed and coalmine methane production. Forth, large coalmines continued to work toward developing coalmine methane resources, although progress was slow and somewhat dependent on outside interest and investment. Sixth, an APEC mission was conducted to fund another coalmine methane recovery and utilization demonstration project in Tiefa Coalmine Co. Ltd., in Liaoling Province of China, that was leading to mercial success of coalmine methane to town gas supply in the city. Seventh, GHGemission reductions under CDM became a new focus—sources of funding for coalmine methane recovery and utilization projects materialized. The last period, 2021–2021 (present), represents China39。s rushing to gold of coalmine methane. Significant features in this period include: (1) petition for large CDM projects drives renewed interest in CMM project development。 (2) truly worldwide class projects, such as Shanxi Jincheng power project (120 MW), were planned and achieved。 (3) many projects were proposed and financed as CDM projects。 (4) a number of pressed natural gas projects using coalmine methane as primary energy were developed。 (5) draining coalmine methane before coal mining became a mandatory national policy in China。 (6) many coalmine owners and operators are using their equities in investing coalmine methane recovery and utilization projects and (7) a number of very important policies on CMM recovery and utilization were effective in this period. These includ
