What’s at stake? If the two sides cannot reach a trade agreement by March 2, the United States plans to escalate the trade war with tariffs on an additional $200 billion of Chinese imports. China has indicated it will similarly retaliate.

Analysis: Trump administration officials claim they have the upper hand as China’s economy begins to buckle under U.S. tariffs. But Mr. Trump may have lost some of that leverage. The nonpartisan Congressional Budget Office estimated that the five-week partial government shutdown cost the economy $11 billion, nearly a quarter of which is permanently lost.

Go deeper: Apple, like many other companies that rely heavily on China to assemble its products, would face significant financial pressure if the trade war escalated and would find it increasingly difficult to move its manufacturing elsewhere. A tiny screw demonstrates why.

Singapore reports vast breach of H.I.V. patients’ data

The medical records and personal information for 14,200 H.I.V.-positive people were stolen by an American and illegally disclosed online, officials said, in the second major data breach of the country’s public health system in two years.

Details: The American, Mikhy Farrera Brochez, lived on an employment pass in Singapore from January 2008 to June 2016, when he was jailed. In 2017, he was convicted of “numerous fraud and drug-related offenses” — including lying to labor officials about his H.I.V. status, providing false information to the police and using forged degree certificates in job applications. He has been deported and his whereabouts was not disclosed.

Why it matters: Half of H.I.V. cases reported in Singapore every year are transmitted through same-sex intercourse, which is illegal there, so the breach is especially sensitive. The country also doesn’t grant employment passes to H.I.V.-positive foreigners.
