Starting on Saturday night, TikTok, the short-form video app owned by the Chinese company ByteDance, was unavailable in the United States as a result of a new law that banned the company’s apps in the country. By around noon on Sunday, it was back.

自周六晚间开始，中国公司字节跳动旗下的短视频应用TikTok在美国停止服务，这是因为一项新的法律在美国封禁了该公司的这一应用。但到周日中午左右，它又恢复了服务。

Though the law calls on ByteDance to sell TikTok to non-Chinese owners or face a ban starting Sunday, TikTok said it was responding to new “clarity” from President-elect Donald J. Trump when it restored service.

尽管这项法律要求字节跳动将TikTok出售给非中国所有者，否则将从周日开始面临禁令，但TikTok表示，它恢复了服务，这是对候任总统特朗普新的“澄清”作出的回应。

Mr. Trump vowed early Sunday to stall the implementation of the ban to give TikTok more time to make a sale that would satisfy the law. It’s still not clear how he’ll be able to do so.

特朗普周日早些时候誓言要推迟实施禁令，以便TikTok有更多时间进行符合法律规定的交易。目前尚不清楚他将如何做到这一点。

What’s happening with TikTok this weekend?

TikTok在周末发生了什么？

TikTok feeds stopped working in the United States late on Saturday night. Instead of videos, the app showed a pop-up message to users that said a law banning TikTok was enacted in the United States and that “President Trump has indicated that he will work with us on a solution to reinstate TikTok once he takes office.” It added, “Please stay tuned!”

周六深夜，TikTok信息流在美国停止运行。该应用没有向用户展示视频，而是弹出了一条消息，称美国一项禁止TikTok的法律已生效，以及“特朗普总统表示，他将与我们合作，在他上任后找到恢复TikTok的解决方案”。它还补充道，“请保持关注！”

Then around noon on Sunday, the app worked again.

随后，周日中午左右，该应用程序再次恢复服务。

“In agreement with our service providers, TikTok is in the process of restoring service. We thank President Trump for providing the necessary clarity and assurance to our service providers that they will face no penalties providing TikTok,” the company said in a statement.

该公司在一份声明中表示：“根据与服务提供商的协议，TikTok正在恢复服务。我们感谢特朗普总统向我们的服务提供商提供必要的澄清和保证，他们不会因提供TikTok而受到处罚。”

In practice, the law penalizes app stores, like Apple and Google, and other internet companies, like Oracle, for distributing or updating any TikTok content.

实际上，该法律规定对分发或更新任何TikTok内容的应用商店（如苹果和谷歌）以及甲骨文等其他互联网公司进行处罚。

Can President-elect Donald J. Trump reverse the ban?

候任总统特朗普能撤回这项禁令吗？

It is not clear if Mr. Trump can stall the ban under the law, but he has vowed to do so. Mr. Trump said on the social media platform Truth Social on Sunday that he would issue an executive order on Monday that would “extend the period of time before the law’s prohibitions take effect, so that we can make a deal to protect our national security.”

目前尚不清楚特朗普是否能根据该法律推迟禁令的实施，但他已发誓要这么做。特朗普周日在社交媒体平台Truth Social上表示，他将于周一发布一项行政命令，“延长该法律禁令生效前的期限，以便我们达成协议，保护我们的国家安全。”

He also said that he planned to arrange a deal that would give the United States a 50 percent ownership stake in a new entity involving TikTok, but it was unclear what shape that would take. “Without U.S. approval, there is no Tik Tok,” he wrote. “With our approval, it is worth hundreds of billions of dollars.”

他还表示，他计划安排一项交易，让美国拥有与TikTok相关的新实体的50%所有权，但目前尚不清楚该交易将以何种形式进行。他写道：“没有美国的批准，就没有Tik Tok。有了我们的批准，它的价值将达到数千亿美元。”

Can he legally do that?

他能合法地这样做吗？

The new law has a provision that says a president can issue a one-time extension of 90 days to the ban, if he or she certifies to Congress that a “qualified divestiture” is underway and that it can take place during that period. But it’s not clear if he can exercise that option now that the law has taken effect. The law was passed by Congress with wide bipartisan support, signed by President Biden and now upheld by the Supreme Court. So to simply subvert it now will raise serious questions.

新法律中有一项规定，总统可以对禁令发布一次性的90天延期，如果他或她向国会证明正在进行“合规的资产剥离”并且在此期间完成。但目前尚不清楚在法律已经生效的情况下他是否可以行使这一选择权。该法律在国会得到了两党的广泛支持，由拜登总统签署，现在也得到了最高法院的支持。因此，现在简单地推翻它将引发严重问题。

Sarah Kreps, the director of the Tech Policy Institute at Cornell University, said that Mr. Trump’s options now are “uncharted legal territory.”

康奈尔大学科技政策研究所所长萨拉·克雷普斯表示，特朗普现在的选择是“未知的法律领域”。

What are the government’s concerns with TikTok?

政府对TikTok有何担忧？

U.S. officials have long been concerned about ByteDance’s ties to the Chinese government. They’ve pointed out that ByteDance could hand over sensitive U.S. user data to Beijing, like location information, noting to laws that allow the Chinese government to secretly demand data from Chinese companies and citizens for intelligence-gathering operations.

美国官员长期以来一直担忧字节跳动与中国政府的关系。他们指出，字节跳动可能会将敏感的美国用户数据（如位置信息）交给北京，并指出法律允许中国政府秘密向中国公司和公民索取数据，以用于情报收集活动。

They are also worried that China could use TikTok’s content recommendations to fuel misinformation, a concern that escalated in the United States after the start of the Israel-Hamas war and during the presidential election.

他们还担心中国可能会利用TikTok的内容推荐来助长虚假信息，这种担忧在以色列与哈马斯战争爆发后以及总统大选期间在美国加剧。

TikTok has long maintained that it has never misused data or spread propaganda at the behest of Beijing in the United States. It has tried to distance itself from ByteDance, which is considered to be one of the world’s most highly valued start-ups, by saying that TikTok’s headquarters are in Singapore and Los Angeles, and that ByteDance is largely owned by global investors. But there are still employees in China that work on TikTok, even though TikTok itself is not used in China.

TikTok长期以来一直坚称，它从未在美国滥用数据，或按照北京的要求在美进行宣传。它试图与字节跳动划清界限，后者被认为是全球估值最高的初创公司之一，TikTok的总部位于新加坡和洛杉矶，字节跳动主要由全球投资者所有。但尽管TikTok本身在中国不能使用，但该公司在中国仍有员工。

Didn’t Trump start all of this in the first place?

这一切不本就是特朗普发起的吗？

Yes. Mr. Trump tried to orchestrate a sale of TikTok to American companies in 2020 and attempted to ban the app — an effort that was ultimately struck down by federal courts. He publicly ​c​hanged his stance on TikTok last March soon after he met with Jeff Yass, a billionaire and Republican megadonor who owns a significant share of ByteDance, though Mr. Trump has said they did not discuss the company.

是的。特朗普在2020年曾试图策划将TikTok出售给美国公司，并试图禁止该应用——这一努力最终被联邦法院驳回。去年3月，在与亿万富翁、共和党巨额捐赠者、拥有字节跳动大量股份的杰夫·亚斯会面后不久，他公开改变了对TikTok的立场，尽管特朗普表示他们没有就该公司进行过讨论。

He also enjoyed his success on the app during the 2024 election, where he now has over 14 million followers. He has credited the app with helping him win young voters. In his message on Sunday, he noted that he wanted TikTok users to be able to enjoy his inauguration on the app.

他还很享受自己在2024年大选期间在TikTok上取得的成功，目前他在该应用上拥有超过1400万粉丝。他认为这款应用帮助他赢得了年轻选民的支持。他在周日发布的信息中指出，他希望TikTok用户能够在这款应用上观看他的就职典礼。
