Negotiators and diplomats from around the world began two weeks of UN climate change talks in Bonn, Germany, on Monday. Their main task is to explore a "technical and operational" implementation road map for the Paris Agreement.

President Xi Jinping has pledged to stick to China's commitments to the accord and the country's low-carbon development strategy underlined at the 19th National Congress of the Communist Party of China last month. French President Emmanuel Macron and German Chancellor Angela Merkel will join the Bonn talks next week to inject their "political will".

Chinese negotiators have called the Bonn talks a "threshold phase" in implementing the Paris agreement, citing the increased global efforts to address the climate threat.
