Japan's Foreign Minister says Tokyo will not demand North Korea change its political system if it gives up its nuclear weapons program. 

Japanese public broadcaster NHK reports that Taro Kono made the remark on Tuesday during a hearing arranged by the foreign affairs and defense committee of the lower house of the National Diet. 

However, Kono emphasized that Japan will not lift its sanctions on the North or begin economic assistance until the regime achieves a complete, verifiable and irreversible denuclearization(CVID), adding that's the international consensus. 

He said what to do with the North's hoarded data regarding its nuclear program and the engineers handling them is also very important. 

Noting recent comments by U.S. State Secretary Mike Pompeo that the U.S. will allow the private sector to invest in North Korea if the North agrees to fully dismantle its nuclear weapons program, Kono said it all depends on what path Pyongyang will take.  

In a joint press conference with South Korean Foreign Minister Kang Kyung-wha following their meeting in Washington last Friday, Pompeo also said if North Korea takes bold action to quickly denuclearize, the U.S. is prepared to work with the North to achieve prosperity on par with South Korea.
