President Obama on Wednesday signed an executive order tightening sanctions on North Korea, the White House announced.

The order came in response to the rogue nation's nuclear test in January and a missile launch it conducted in February.

"These actions are consistent with our longstanding commitment to apply sustained pressure on the North Korean regime," press secretary Josh Earnest said in a statement. 

"The U.S. and the global community will not tolerate North Korea’s illicit nuclear and ballistic missile activities, and we will continue to impose costs on North Korea until it comes into compliance with its international obligations."
 
The move also came amid reports that North Korea sentenced an American student to 15 years of hard labor for stealing a political banner during a trip to Pyongyang.
