One of China's elite figures has suddenly disappeared after criticising Xi Jinping online.
A prominent economist at one of China's leading think tanks has been investigated, detained and suspended.
He was suspected of criticizing Chinese leader Xi Jinping in a closed chat, the Wall Street Journal writes.
The economist's disappearance comes amid a protracted economic slowdown in China.
A Chinese economist has closely studied the president's decisions and expressed his disagreement in a closed chat.
This led to his arrest, removal from office and criminal prosecution.
Before losing his job, the economist was deputy director of the Institute of Economics at the state-run Chinese Academy of Social Sciences.
He worked for the organization for more than two decades, working on health care reforms.
His last public appearance was at the end of April at an industry conference on the elderly.
