In the negotiations under the climate convention (UNFCCC), China has been a leading advocate for maintaining the principle of "common but differentiated responsibilities". The principle holds that while all countries are responsible for contributing solutions to climate change, it is the capability to deal with climate change that determines the nature and extent of those responsibilities. Claiming to still be a developing country with limited capabilities, China has managed to avoid taking on absolute targets and to maintain the right to flexibility for developing countries on a range of topics, including monitoring, reporting and verification of emissions. Through the years of international climate negotiations, a considerable part of China’s climate diplomacy has aimed at keeping this division between developed and developing countries, so as to avoid absolute reduction targets. With the signing of the Paris Agreement, China committed to peak its carbon dioxide emissions by 2030 and to curb emissions per unit of GDP by 60%–65% compared to the 2005 level.
