The United States and China are working on an international agreement promoting the use of biofuels to strengthen energy security and reduce greenhouse gas emissions. The agreement, which calls for cooperation in research for producing biofuel crops, could be announced by December of this year. United States Assistant Energy Secretary, Alexander Karsner said, “Through our agreement with China, we hope to transfer this knowledge and expertise. " We had a very productive, lengthy and engaging dialogue on a wide range of issues, things of mutual concern like energy markets, global climate change, price of oil and studies of science and technology between the two countries.”.
