In December 2013, China and the United States announced that they would undertake a reciprocal peer review of their fossil-fuel subsidies under the auspices of the G20. These peer reviews were the first of their kind in the G20. Other countries and international organisations were invited to take part in the review. In the case of China, those invited participants were (in addition to the United States): Germany, Indonesia, the IMF, and the OECD. In the case of the United States, those invited participants were (in addition to China): Germany, Mexico, and the OECD. The OECD was also asked to chair both reviews, and to act as a co-ordinator and facilitator among the participants. These peer-review processes were finalished in 2016 and the outcomes published in September 2016 at a G20 meeting in China. The links below provide access to the reports.
