President Trump's Twitter account may be popular among his fans at home, but his latest missives are complicating the work of American diplomats overseas. As some diplomats push back, State Department spokeswoman Heather Nauert cautions that they "are expected to use their judgment."

Consider Trump's personal attack on London's mayor, Sadiq Khan, after Saturday night's deadly terrorist attack in the British capital.

A Chinese labor activist has been arrested and two others have disappeared after investigating alleged labor abuses at a factory that makes shoes for several major brands — including Ivanka Trump's.

Hua Haifeng disappeared sometime Sunday while en route to the Huajian International shoe factory in southern China.

On Tuesday, police in the province called Hua's wife, Deng Guimian.

An American THAAD missile defense system is now operational in South Korea, less than two months after its components arrived there, the U.S. military says.

The system is meant to protect South Korea from ballistic missiles fired by North Korea, the Pentagon says. But China and other critics of the move say it will only increase tensions on the Korean Peninsula. The decision to install the missile shield was made by the U.S. and South Korea last July.

During a "very friendly" phone conversation, President Donald Trump invited Philippines President Rodrigo Duterte to the White House, signaling a massive shift in attitude from the U.S. toward a leader known best for inciting an extrajudicial war on drugs in his country that's killed more than 7,500 people.

President Trump says that while he would like to resolve the issue of North Korea's nuclear program diplomatically, it will be hard — and there is a potential for a major clash with the Asian nation, Trump said in an interview with Reuters.

"There's a chance that we could end up having a major, major conflict with North Korea, absolutely," the president told the news agency. "We'd love to solve things diplomatically but it's very difficult."

In his first interview with NPR, Secretary of State Rex Tillerson has a wide-ranging interview with Morning Edition's Steve Inskeep.

Steve Inskeep: I want to begin with North Korea. We heard when you said, "the era of strategic patience is over," so we know what your policy is not. Is there a word or phrase you can give us to say what your approach to North Korea is?

Secretary of State Rex Tillerson: Yes, our approach to North Korea is to have them change their posture towards any future talks.

China's Foreign Ministry is defending a decision to grant Ivanka Trump new trademark rights for her line of handbags, jewelry and spa services. The three new trademarks were approved April 6 while the president's daughter and her husband, Jared Kushner, sat next to Chinese President Xi Jinping and his wife at dinner at President Trump's Mar-a-Lago resort in Florida, according to The Associated Press.

For someone who speaks with as much conviction as President Trump, he sure has a way of changing positions with an equal level of certitude.

Donald Trump's rhetoric on China and trade has been blunt, to say the least.

"We can't continue to allow China to rape our country — and that's what they're doing," he said at a May 2016 campaign rally. "It's the greatest theft in the history of the world."

What President Trump may refer to as "the art of the deal," his guest at Mar-a-Lago on Thursday and Friday — Chinese President Xi Jinping — might call "win-win cooperation."

In this first summit meeting between the two leaders, both sides have things they are willing to give and get. Both will be sizing the other up to see to what extent they can do business with each other.

Chinese President Xi Jinping will visit President Trump in Palm Beach, Fla., next week, for talks that will likely range from economic to security issues. The first meeting between the two leaders will stretch from April 6-7.

Last year, the U.S. trade deficit with China topped $347 billion, with total trade worth more than half a trillion dollars, according to the U.S. Census Bureau.

A Chinese spokesperson notes that before the visit to Trump's Mar-a-Lago property, Xi will spend three days in Finland.

Secretary of State Rex Tillerson says the U.S. doesn't want to take military action against North Korea, but "all of the options are on the table" if a serious threat arises. Tillerson made his frank remarks in a visit to South Korea on Friday, a day after saying diplomatic efforts "have failed" to persuade North Korea to abandon its nuclear program.

Tillerson's Asia tour began in Japan and will end in China. The top American diplomat is traveling without a press contingent.

The head of the president's National Trade Council this week offered a decidedly bleak and suspicious view of global trade. Peter Navarro says foreign companies buying up U.S. corporations are posing a threat to national security.

That might sound bad, but it's a fringe view that puts him at odds with the vast majority of economists.

President-elect Donald Trump has used Twitter — his preferred means of communication — to weigh in on a swath of foreign policy issues over the past few weeks.

DAVID GREENE, HOST:

Pretty extraordinary few days in the relationship between the United States and China, all, of course, amid the uncertainty of a presidential transition here in the United States. Last week, China seized a U.S. drone in international waters.

On Sunday, President-elect Donald Trump told Fox News that he wouldn't feel "bound by a 'One China' policy unless we make a deal with China having to do with other things, including trade."

The One China policy has guided U.S.-China discourse since 1979, when Washington established diplomatic relations with Beijing and downgraded its embassy in Taiwan.

President-elect Donald Trump's phone call with the president of Taiwan last week, initially characterized by Trump transition staffers and Taipei officials as just a small courtesy, has emerged as part of a lobbying strategy by a quintessential Washington insider.

Former Sen. Bob Dole, a war hero, lion of the Senate and 1996 Republican nominee for president, was an early supporter of Donald Trump, even when other Republican leaders were still wary.

President-elect Donald Trump has tapped Iowa Gov. Terry Branstad to serve as U.S. ambassador to China, the transitional office confirmed Wednesday.

The longest-serving governor in U.S. history, Branstad has extensive ties to China and a close friendship with the Chinese President Xi Jinping that goes back decades.

The revelation of a phone call between President-elect Donald Trump and Taiwan President Tsai Ing-wen last Friday startled leaders and diplomats in Washington, Beijing and beyond. In her first comments on the call, Tsai sought to dampen those fears.

"Of course I have to stress that one phone call does not mean a policy shift," Tsai said on Tuesday in a small meeting with American journalists in Taipei. "The phone call was a way for us to express our respect for the U.S. election as well as congratulate President-elect Trump on his win."

President-elect Donald Trump's unprecedented call with Taiwanese president Tsai Ing-wen has brought all varieties of foreign policy wonks out of the woodwork. Most are critical — some are mocking — of the president-elect's break with four decades of diplomatic protocol.

The past couple of weeks have seen U.S. and Chinese warships holding maneuvers in the South China Sea, and the president of a country that's a U.S. treaty ally, the Philippines, snubbing the U.S. and aligning himself with China.

Some observers see all of this as a blow to the U.S. strategic position in Asia, and further evidence of a looming showdown between the U.S. and China.

U.S. Ambassador to China Max Baucus, however, remains upbeat about the relationship.
