American companies can rest assured that they can still do business with wechat in China. Two weeks ago, trump banned the service from Tencent, a Chinese company. According to people familiar with the matter, senior government officials have been in touch with some companies in recent days, recognizing that a total ban on wechat could have a devastating impact on US technology, retail, gaming, telecommunications and other industries. < / P > < p > Apple will be one of the companies likely to suffer the most from the wechat ban, as China contributes a fifth of its revenue. In addition, a large part of Apple’s manufacturing business relies on China, and if the Chinese government decides to reverse, Apple may be affected. The U.S. government is still working on the technical issue of how to implement a partial ban, according to a person familiar with the matter who declined to be named. At the same time, a key question is whether the White House will allow apple and Google to provide wechat downloads in global app stores outside the United States, and if so, which regions will be involved. < / P > < p > one of the people familiar with the matter said senior government officials were considering the scope of the trump ban, which could eventually overturn any of their decisions. < p > < p > three of them said that officials did not expect wechat to disappear completely in the United States, but their goal was to ban any download or update of wechat in the United States. < / P > < p > for example, if wechat has been installed on the mobile phone of passengers entering the United States, they may be able to use it, but they will not be able to update it. This means that if a non US resident stays in the US for a long time, the version of wechat he uses will become old-fashioned over time, according to people familiar with the matter. < / P > < p > if wechat is partially banned, it may mean that apple and other companies can provide the program in China’s app stores, while Starbucks and other companies can continue to sell coffee or accept payment through wechat in China. The government intends to ban downloading or updating wechat apps in US app stores, according to two people familiar with the matter. According to people familiar with the matter, U.S. companies and their lobbyists have stepped up their campaign in recent weeks to ask White House and commerce department personnel about the operation and intent of the executive order. < / P > < p > “we are communicating with all those who are willing to listen to us,” said Craig Allen, President of the American Chamber of Commerce in China. Members of the chamber include Wal Mart and general motors. “Wechat is like electricity. It’s going to be used in every aspect [in China] < / P > < p > people familiar with the matter said questions raised by lobbyists included whether the order would prohibit U.S. companies with business in China or their Chinese subsidiaries from accepting payments via wechat. People familiar with the matter also said the term “lobbying” was more clearly defined. Representatives of the National Retail Federation and the association of retail leaders representing companies such as best buy, target and Lowe’s are among the lobbyists who ask questions to the government, according to people familiar with the matter. < / P > < p > wechat, with more than one billion users, is the most popular communication application in the world. Even if wechat is banned only in the United States, personal communication between China and the United States may be blocked. At the same time, it will disrupt the operation of international companies that rely on wechat to carry out transnational business. < p > < p > after trump issued the executive order on August 6, Tencent’s share price fell by 10%, and its market value evaporated by nearly 35 billion US dollars, as investors worried that Tencent’s game business and other business interests in the United States might also be threatened. Tencent holds a large stake in Epic Games Inc., a developer of fortrite, and riot games Inc., a developer of the League of heroes. It also invests in Uber Technologies Inc. and snap Inc. The next day, Tencent hired former Treasury adviser Roberto Gonzalez as its first lobbyist in Washington, according to a federal document.
