美国有线新闻 CNN 美国联邦运输安全管理局禁止雇员用抖音（在线收听）

Which of these social media networks is owned by a Chinese company? Pinterest, TikTok, WhatsApp or Snapchat. All of these networks are owned by American companies except TikTok which was launched in 2016.

下列哪个社交媒体网络归中国公司所有？品趣志、抖音、WhatsApp还是Snapchat？上述网络除2016年推出的抖音外均归美国公司所有。

Today TikTok has hundreds of millions of users around the world. But there are new restrictions on how U.S. government workers can use the app. As of this week the Transportation Security Administration says TikTok may no longer be used for its social media outreach. The TSA is responsible for keeping America's airports secure. It employs around 50,000 security officers to help do this. And the agency says it uses several social media platforms to communicate with Americans.

如今，抖音在全球拥有数亿名用户。但规定美国政府工作人员如何使用该应用的最新限制措施已经出台。美国运输安全管理局（简称TSA）表示，从本周开始，抖音可能不再用于社交媒体推广。美国运输安全管理局负责保障美国机场的安全。该机构雇佣了约5万名安全官员来协助完成这项工作。该机构表示，他们使用多个社交媒体平台与美国民众交流。

Like other apps, TikTok collects information about the people who use it. But because TikTok is owned by a Chinese company and because there are laws in China that require companies to cooperate with the intelligence work of the Chinese government some U.S. security experts and lawmakers have said using TikTok could cause problems for America's national security.

与其他应用程序一样，抖音会收集用户的相关信息。但由于抖音是一家中国公司，而且中国法律要求企业配合中国政府的情报工作，一些美国安全专家和议员认为，使用抖音可能会对美国的国家安全构成问题。

The TSA says it's never had an official TikTok account but that a small number of its employees have used the app to make videos for the agency's social media outreach. That's not allowed anymore. The TSA is joining the Department of Defense, the State Department and the Department of Homeland Security in putting restrictions on how their employees can use TikTok.

美国运输安全管理局表示，其从未注册过官方抖音账号，但有一小部分工作人员使用抖音为该机构的社交媒体推广制作视频。这是不允许的行为。美国运输安全管理局将加入美国国防部、国务院以及美国国土安全局的阵营，对员工如何使用抖音施加限制。
