Foxconn, the world's largest contract electronics maker, is considering setting up a display-making plant in the United States in an investment that would exceed $7 billion, company chairman and chief executive Terry Gou said on Sunday. The plans come after U.S. President Donald Trump pledged to put "America First" in his inauguration speech on Friday, prompting Gou to warn about the rise of protectionism and a trend for politics to underpin economic development. Foxconn's proposal to build a display plant, which would be planned with its Sharp Corp unit, depend on many factors, such as investment conditions, that would have to be negotiated at the U.S. state and federal levels, Gou told reporters on the sidelines of a company event.
