Foxconn is a major supplier to Apple Inc (AAPL.O). China is the base for its assembly of Apple's iconic iPhones, and where Foxconn employs about a million people.

"Foxconn is also in the running as a suitor for Toshiba Corp's (6502.T) chip business. People familiar with the deal have told Reuters that Foxconn is considered a U.S. security risk due to ties with China.

Reuters earlier reported that Japanese display maker Sharp Corp (6753.T) may start building a $7 billion plant in the United States in the first half of 2017, taking the lead on a project initially outlined by its Taiwanese parent Foxconn."
