U.S. Secretary of State Rex Tillerson says there are "clear signs" that international sanctions imposed against North Korea are beginning to impact the country's economy.
 
Tillerson, who accompanied President Donald Trump on a visit to China, made the remark on Thursday during a media briefing after summit talks between Trump and Chinese President Xi Jinping in Beijing.

"There are clear signs, and the Chinese side has shared with us some of the signs they're seeing. We see certain signs with our own human intel and other sources we have."
 
Tillerson added that the sanctions are creating some stress within North Korea's economy and with some of their citizens, potentially even with some of their military.
 
CNN reported that the comments mark the first time the U.S. has indicated that the latest UN sanctions are beginning to affect North Korea's economy.
