WASHINGTON—U.S. and Chinese representatives are meeting Thursday to try to save sinking trade negotiations before a planned tariff hike Friday on $200 billion in Chinese goods. President Donald Trump said Wednesday night that the two sides expected a positive outcome from the talks until recently, when “China broke the deal” by attempting to renegotiate key points. Tariffs will climb from 10 percent to 25 percent at 12:01 a.m. Friday if the trade envoys don’t make progress at their meeting Thursday.

Some drivers for ride-hailing company Uber turned off their apps on Wednesday morning to protest low wages ahead of the company’s initial public offering on Friday. Demonstrations took place in 10 U.S. cities, including Chicago, Los Angeles, New York, San Francisco, and Washington, as well as some European locations. It was unclear how many drivers participated in the strike, and its effect on customers seemed minimal.

A technical problem with a third-party vendor caused systemwide delays for U.S. airlines on Monday. Airports in Atlanta, Boston, Chicago, Dallas, Detroit, Miami, New York, and Washington, D.C., experienced backups related to AeroData, which provides aircraft location and weight balancing technology, according to American Airlines. The Federal Aviation Administration said the problem affected several carriers and told travelers to contact airlines directly for updates. Southwest Airlines lifted an internal ground stop just after 7 a.m. and anticipated delays throughout the day.

Lawmakers on Capitol Hill grilled government officials in hearings Wednesday about what could have been done to prevent the two recent air tragedies that killed a total of 346 people aboard U.S.-manufactured planes. Acting Federal Aviation Administration Administrator Daniel Elwell told members of the Senate Aviation Subcommittee that his agency would have to hire 10,000 more workers and spend another $1.8 billion if it wanted to stop delegating duties to aircraft makers.

LifeWay Christian Resources announced Wednesday it will close all 170 of its retail stores this year and focus on digital sales. In January, the publishing arm of the Southern Baptist Convention said it would reduce its brick-and-mortar locations due to declining customer traffic and sales. “While we had hoped to keep some stores open, current market projections show this is no longer a viable option,” acting President and CEO Brad Waggoner said in a statement.

After pushback from local politicians, Amazon said it will no longer build a headquarters in New York City. The Seattle-based online retailer spent a year conducting a highly publicized search in which cities tried to woo the company with promises of favorable tax policies. In November, Amazon announced it would split its expansion between New York and Northern Virginia, but some New York politicians were unhappy with the nearly $3 billion in tax incentives promised to the retailer.

Amazon CEO Jeff Bezos in a blog post Thursday claimed to be the target of extortion and blackmail by the publisher of the National Enquirer. Bezos, 55, said the tabloid threatened to publish explicit personal photos of him unless he stopped investigating how the Enquirer obtained texts between him and his mistress. The National Enquirer on Jan. 9 published a story about Bezos and his affair with former TV anchor Lauren Sanchez, who is married. That same day, Bezos announced on Twitter that he and his wife of 25 years, MacKenzie Bezos, were planning to divorce.
