China

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."

The drug is so strong and deadly, it's been researched as a chemical weapon of warfare; police officers are warned to handle it with extreme care. The opioid carfentanil is 10,000 times more potent than morphine — but until now, it hasn't been a controlled substance in China, where producers have been exporting it abroad.

Two days before the election, Donald Trump stood before a large crowd in Sioux City, Iowa, and called onstage the longest-serving governor in U.S. history.

"I think there's nobody knows more about trade than him," Trump said of Iowa Gov. Terry Branstad. "Boy, you would be our prime candidate to take care of China."

Almost a million elephants roamed Africa 25 years ago. Assessments of their population now vary but suggest there are fewer than half that many. The main reason for the decline is ivory. Despite a 1989 ban on ivory trade, poachers continue to kill elephants for their tusks.

Now China, the destination for most of that ivory, has announced it will shut down its domestic ivory market.
