China will work to achieve its existing greenhouse gas targets and strive to do better as the challenges of climate change become more urgent, Xie Zhenhua, the country's top climate envoy, said at a briefing Monday.
"I believe the promises we make will be 100 percent completed and we will strive to do better," said Xie, speaking to reporters before a new round of climate talks in Katowice, Poland, on how to implement the 2015 Paris agreement.
"Although we have encountered a lot of difficulties, a lot of problems, our targets and our resolution will not change," he added.
