Ross also said that the company will have to replace its entire management and board of directors as part of the deal.

The company has 20 USA offices or research centers and has sponsored five National Basketball Association teams.
Despite the settlement, there was no sign Trump had veered from plans this month to impose as much as $50 billion in tariffs on Chinese imports to punish Beijing for its alleged theft of American technology and know-how.
