U.S. President Donald Trump on Friday downplayed a revenue warning from Apple Inc that cited slowing sales in China and said China's weakening economic growth puts the United States in a strong position as negotiators from the world's two largest economies prepare for trade talks next week.

Trump has slapped import tariffs on hundreds of billions of dollars of Chinese goods as he seeks concessions from Beijing on issues ranging from industrial subsidies to hacking, sparking retaliation by China. The measures have disrupted trade, hurt manufacturing, roiled international markets and slowed the global economy.

U.S. officials are heading to Beijing next week for the first face-to-face talks since Trump and China's President Xi Jinping in December agreed to a 90-day truce in the trade war as they sought to strike a deal.
