古巴代表团在美国总统特朗普演讲期间退出联合国大会。

U.S. Secretary of State Rubio said the Biden administration had been eager to reach an agreement with Iran, making repeated concessions over four years to try to secure a deal, but ultimately failed.

On Sept. 22 the Ministry of Ecology and Environment (MEE) said it completed a five-year national assessment of ecological protection redlines. Major ecological-security and strategic regions — including the Yangtze Economic Belt, Yellow River Basin, Qinghai‑Tibet Plateau, Qinling, coastal zones, Jing‑Jin‑Ji, Yangtze River Delta and the Guangdong‑Hong Kong‑Macao Greater Bay Area — showed improving environmental trends. Redline areas remained stable, ecosystem-service functions overall strengthened, and key indicators — water conservation, biodiversity protection and vegetation cover — rose. Water and air quality continued to improve, no major ecological-destruction events or sudden environmental incidents occurred, and the redline institutional framework has been put into effect.
