Virginia - Republican presidential candidate Donald Trump said he will push for companies including Apple to bring manufacturing back to the United States.
"Make America great again," Trump said in a speech at Liberty University in Virginia.
"We’re going to get things coming. We’re gonna get Apple to start building their damn computers and things in this country instead of in other countries.”
Apple does research and design at its headquarters in Cupertino, California but now manufactures most of its iPhones, iPads and Macintosh computers through partners in countries such as China.
Apple made and assembled many products in the US until the late 1990s, and then shifted manufacturing to Asia to take advantage of the region’s industrial base and lower labour costs.
Chief Executive Officer Tim Cook has made attempts to bring manufacturing work back to the US, including a 2012 effort to invest $100m in domestic capabilities. Still, he has said it’s difficult to make broad changes because of declining expertise in skills such as tool-and-die manufacturing in the US.
