North Korea FM, Zarif Confer

North Korea’s top diplomat held talks in Tehran on Tuesday on a range of issues, including bilateral ties and regional and international developments. 
Foreign Minister Mohammad Javad Zarif met with his North Korean counterpart, Ri Yong-ho, as the US has stepped up its political and financial pressure over Iran’s civil nuclear program while calling on the North to be denuclearized. 
Ri is in Tehran following his attendance at a meeting of foreign ministers of the Association of Southeast Asian Nations in Singapore, where he lashed out at the US for “alarming” actions, including “raising its voice louder for maintaining the sanctions against” North Korea,  Reuters reported.  
The US is pushing Pyongyang to denuclearize after the summit between President Donald Trump and North Korean leader Kim Jong-un.
