North Korea and China are reportedly working together more closely to arrest North Korean defectors in China.
Voice of America cited numerous sources as saying... the ways North Korea and China's cooperate are becoming more diversified,... and include sending defectors to South Korea to work as spies.
VOA also reported that there has been a growing number of cases where a captured defector will be released to infiltrate another group of North Korean defectors to leak information and have them caught.
The report said the allies' closer cooperation is why 7 defectors were recently caught by the Chinese police.
They're now at risk of being sent back to the North.
