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. As planned, the new presidential executive order will take effect next month, banning U.S. companies from "any transaction that is related to WeChat."
Bryant also cautioned against a disruption in cross-border investment, as her company helps bring in investment from around the world, especially China.
WeChat users in the U.S. rushed to install the app before it could disappear from the app stores. They have also turned to QQ, as the ban did not specifically cover this product.
Other participants in the call included Procter & Gamble Co, Intel Corp, MetLife Inc, Goldman Sachs Group Inc, Morgan Stanley, United Parcel Service Inc, Merck & Co Inc and Cargill Inc.
Apple will be put into a very difficult situation if it is forced to remove WeChat from its App Store.
