The United States is absent from the COP30 climate summit, while China is strengthening its influence by promoting its clean energy technologies and facilitating negotiations.

For the first time in nearly 30 years, the United States is not participating in the annual UN climate summit, giving China the opportunity to assert itself as a leader in the fight against climate change. China's pavilion at COP30 in Belem, Brazil, draws attention through its presentations of clean energy companies and the active role of Chinese diplomats in negotiations, replacing the traditional influence of Washington.

China's rise in renewable energy and electric vehicles strengthens its political position, while the absence of the US, under President Trump's leadership, is seen as an opportunity for Beijing. Critics warn that the lack of an official US delegation allows China, the largest emitter of greenhouse gases, to advance in the green energy industry. China's centrally located pavilion promotes sustainable technologies and partnerships with countries in the Global South. Although China takes on a coordinating role in negotiations, some experts emphasize that its leadership remains limited without more ambitious commitments to reduce emissions.
