As world leaders arrive in Madrid for a second week of climate talks, missing among the familiar faces will be Xie Zhenhua, China’s climate negotiator for over a decade. In his place, Zhao Yingmin, vice minister of ecology and environment, will head the Chinese delegation.
There’s unlikely to be an official announcement but multiple sources say that Xie has left his position as the country’s special representative on climate change. Xie has steered China’s climate diplomacy since 2007, and has been critical to forging agreement on international climate action to avoid dangerous global warming.
According to a special report by Li Jing in Dialogo Chino, China has become the world’s largest annual emitter of greenhouse gases over the past decade. Yet in that time the country has also shifted from stubbornly defending its right to uncontrolled emission growth to actively embarking on a low-carbon path.
That transformation has become a national strategy and Xie Zhenhua’s personal role as a facilitator has been indispensable according to former colleagues, fellow negotiators and civil society representatives.
Xie Zhenhua became vice chair of China’s top economic planning body, the National Development and Reform Commission (NDRC) in 2007. The NDRC was also in charge of climate policy until these powers were moved to the Ministry of Ecology and Environment (MEE) in 2018 as part of wide-ranging ministerial changes.
Xie is known as a candid, tough negotiator in international climate talks. At the Durban climate summit in 2011, he repeatedly banged a table in remonstration with rich countries over what he believed were hypocritical demands on China to accept binding emission reduction targets. The moment was widely broadcast on Chinese television.
The scene set the tone of Xie’s early tenure as China’s top climate diplomat: a tenacious negotiator in defence of “China’s right to development.” In the years before and immediately after the fateful 2009 Copenhagen climate talks, China engaged with industrialized nations in fierce, sometimes disparaging debates over how the burdens of addressing global warming should be shared.
The impasse between the US and China, which jointly emitted nearly 40% of the world’s greenhouse gases that year, was particularly fiery. The deadlock at Copenhagen resulted in a political statement and a resounding sense of failure rather than a binding deal.
The accounts of Copenhagen by China and the US were bitter. Xie criticized rich countries for “conspir[ing] to divide developing nations,” while his counterpart Todd Stern, who served as the US special climate envoy from 2009 to 2016, described the summit as “snarling, aggravated and chaotic.”

Despite the difficult start to their working relationship, Xie and Stern developed a personal bond. They visited each other’s hometowns of Tianjin and Chicago and even watched a baseball game together. They describe each other as “old friends.”
He’s colourful and interesting, “has a sense of humour and loves to laugh. I kind of liked him right away,” Stern told China Dialogue.
Stern added that China and the US came to climate negotiations from very different places, making it natural for Xie and himself to struggle through various issues – even to bang heads – but over the years they learned where each other’s red lines were.
“He really understands the issues. He is very protective of what he sees as China’s interests.”
Stern described Xie as a tenacious negotiator and a good listener. These qualities helped him win the trust of his counterparts in other major developing countries. He could smooth things out when negotiations entered critical phases. “He was able to persuade other developing countries. I guess there’s no one more influential than him,” said Stern.
In the final hours of last year’s annual climate summit in Katowice, Poland, discussions on rules to implement the Paris Agreement came to a deadlock when countries could not agree on provisions for a global carbon market mechanism, due to opposition from Brazil. The whole package was in danger of collapse under the usual practice at UN negotiations that “nothing is agreed until everything is agreed.”
In an interview with China Central Television, Xie said the conference chair entrusted the Chinese delegation to communicate with other parties. “After six-hour discussions … we were able to overcome the last obstacle for reaching a compromise,” Xie said of the decision to move the carbon market discussions to this year’s climate summit to allow the Paris rulebook to pass.
Stern said that while Xie was protective of national interests – as every negotiator would be – he also cares deeply about the environment. “We might have had very different views on what needed to be done, but I never doubted that he came to the negotiations caring about climate change and wanting things to be done,” he said.
Within China’s climate community, Xie is known for a personal commitment to the issues that goes far beyond the negotiating table. He visited small island nations, including Tuvalu and Fiji, as well as the polar regions.
“I have witnessed climate impact on glaciers and the suffering of polar bears,” Xie told Tsinghua students in a recent speech.
During his tenure, China’s stance on climate has shifted increasingly from a defence of its “right to emit” to a promotion of low-carbon development as a national strategy.
The old narrative that dominated Chinese media around 2009 – that climate change was a conspiracy by developed countries to contain the country’s rise – effectively disappeared in subsequent years. It was replaced by a growing call for an “energy revolution,” entailing a massive deployment of renewable energy and a decisive break from burning coal.
Coal consumption in the past two years has rebounded but not returned to the level seen in 2013-2014, which many experts believe was a peak that China will not return to. Furthermore, coal’s share of the energy mix in China has dropped sharply from 72% in 2005 to 59% in 2018.
Such a major shift in energy policy is not one man’s making. It coincided with a worsening air pollution crisis that pressured China’s leadership into bold emission cuts. But observers, including former colleagues in government that asked not to be named, believe that the changes would have been unimaginable without Xie’s contribution.
As vice-chairman of NDRC, Xie was able to leverage the international pressures he was personally exposed to and push for changes to mainstream climate policies at home. As a ministerial-level official, his personal commitment carried weight in key policies such as the creation of a national carbon market, the observers said.
“Xie’s career will be remembered for his leadership and dedication to the sustainable development of the country,” said Li Shuo, senior global policy advisor with Greenpeace East Asia. “His effort evidences the power that a committed individual can have to create change and to shape the world’s perception of China. That is perhaps his greatest legacy.”
Xie’s career as a senior climate diplomat has come to an end, but he has not left the stage entirely. In 2017, he donated the prize money from his Lui Che Woo award to his alma mater Tsinghua University in the hope that the HK$20 million (US$2.5 million) would help foster the next generation of climate leaders in China. He currently serves as the president of the university’s Institute of Climate Change and Sustainable Development.
The mantle of head of the Chinese delegation has been passed on to Vice Minister Zhao Yingmin, s protégé of Xie Zhenhua. But a number of observers have questioned whether China’s leadership will retain a special representative for climate change, a position that carries a broader mandate and greater diplomatic flexibility than vice minister.
This could affect China’s climate diplomacy at a time when most countries must deliver a step change in their commitments to reduce emissions to meet the Paris Agreement 2C target.
