China’s People’s Liberation Army conducted an unannounced missile test on Sunday, which was picked up by Chinese social media. Collin Koh, a military analyst at RSIS, said that media hype after the launch, which was deliberately left uncorrected, had been used to address public ­concerns and expectations in China. “Sometimes it’s difficult to conceal military activities and missile launches can be observed by the public, such as the rocket trails and light,” Koh said.
