The International Monetary Fund has revised down its outlook for global economic growth this year. It says behind the change is the growing trade friction caused by US tariffs and retaliation by some trading partners.



The IMF now expects the world economy to grow 2.8 percent. That's down from its previous projection in January by 0.5 percentage points.



The latest forecast is based on data up to April 4, including the announcement by the Trump administration of what it calls "reciprocal" tariffs.



Japan's growth stands at 0.6 percent, down 0.5 points.



The figure for the United States is 1.8 percent, marking a significant drop of 0.9 points. This is largely due to greater policy uncertainty and a softer demand outlook.



China's economy is projected to grow by 4 percent, down 0.6 points.



The IMF says that worsening trade friction might continue to depress growth, and financial conditions could further tighten.
