Miliband represented the UK at the 2009 Copenhagen Summit, from which emerged a global commitment to provide an additional US$10 billion a year to fight the effects of climate change, with an additional $100 billion a year provided by 2020. The conference was not able to achieve a legally binding agreement. Miliband accused China of deliberately foiling attempts at a binding agreement; China explicitly denied this, accusing British politicians of engaging in a "political scheme".
