The U.S.-based International Monetary Fund says global economic growth will be better than expected despite a slowdown in the U.S. economy over fluctuating tariffs imposed by President Donald Trump.

The International Monetary Fund says the global economy is weathering President Trump's trade policy revolution, with growth expected to reach 3 percent this year.

The International Monetary Fund (IMF) has predicted stronger global economic growth than it forecast in April in part due to some US tariffs on goods being softened. A surge in US imports as firms tried to beat impending higher import taxes and actions by some governments to boost growth bumped up its latest forecast.
