Ma Jian has a flair for the provocative. In 2012, the London Book Fair partnered with the all-powerful Chinese state agency responsible for regulating publications and the Internet—the General Administration for Press and Publication. In protest, the author smeared an X across his face in red paint. He then attempted to hand a copy of a book he had written, its cover also marked with a red X, to the head of the agency, who was attending the fair. The book was about one of China’s most taboo topics—the 1989 massacre in Tiananmen Square.

Ma had reason to be angry: his books have been banned in his homeland for the last 30 years, and he has not been allowed to return to China for the last few years as the country’s President, Xi Jinping, has initiated a widespread crackdown on dissent.

The author was born in the Chinese city of Qingdao in 1953. He started his career on a more traditional path, at a petrochemical plant in Beijing, before deciding to become a photojournalist. In the 1980s..

Visitors to Hong Kong’s History Museum can take the subway to the city’s Tsim Sha Tsui neighborhood, a bustling tourist and shopping district.

From there, it’s a short walk through markets with stalls hawking cheap clothing and electronic goods to an unmarked doorway of a nondescript commercial building lodged between a gas station and a noodle shop. Inside is the world’s only museum dedicated to the events of June 4, 1989.

The door to the June 4 Museum was easy to find on Friday aftern..

North Korean officials billed the U.S. $2 million for the medical care of comatose American Otto Warmbier before allowing him to be flown home from Pyongyang, the Washington Post reports.

President Trump has previously denied that his administration has paid any sum of money for the release of U.S. hostages in the pariah state.

According to the Post, State Department envoy Joseph Yun, who was in Pyongyang to take Warmbier home in June 2017 following news of his poor health condition, was instructed by North Korean officials to sign the agreement. Yun reportedly did so upon direction from Trump via then-Secretary of State Rex Tillerson.

The bill then went to the Treasury Department, the Post says, citing two unnamed people familiar with the situation. It is unclear whether the bill was ever paid.

University of Virginia student Otto Warmbier, at the time 21, arrived in North Korea in late December 2015 on an organized tour of the state. After spending five days there, he was arrested..
