In the U.S., WeChat app downloads in the U.S. rose by 41 percent in a six-day average from the week prior to the U.S. ban announced last Thursday, and QQ downloads have tripled in the past week, according to data from Sensor Tower.
Apple Inc., Ford Motor Co., Walmart Inc., and Walt Disney Co. were among those represented in the call in which they expressed their anxiety that competitiveness in China may be undermined by the order.
