In June, the Paris-based organisation had cut its forecast from 3.1 percent to 2.9 percent, warning at the time that Trump's tariffs would stifle the world economy. The OECD said "front-loading" -- companies rushing to import goods ahead of Trump's tariffs -- "was an important source of support". The economy also got a boost from strong AI-related investments in the United States and government spending in China. The OECD also upgraded the growth outlook of the United States for 2025 from 1.6 percent to 1.8 percent. The OECD raised the growth outlook of other major economies: to 4.9 percent in China, 1.2 percent in the eurozone and 1.1 percent in Japan.
