Last week I went to a very unique session on North Korea which featured a rare appearance of a North Korean diplomat, at London-based policy institute Chatham House.

A wide range of topics — from North-South relations, human rights, a potential nuclear test to a new generation of young diplomats — were discussed, but  under the so-called Chatham House rules (meaning I cannot reveal who said what).

Participants discussed how Pyongyang’s relationship with South Korea and the United States has been deteriorating as both sides exchange some pretty acrid verbal attacks. For instance earlier this month North Korea’s official KCNA called  South Korean President Park Geun-hye a “political prostitute” while it described U.S. President Barack Obama as a “wicked black monkey”.  South Korean Ministry of Defence spokesman Kim Min-seok for his part, had retorted that North Korea wasn’t a real country and that it existed solely to prop up a single person.

The North’s argument is that all those abusive comments were made by members of the North Korean public and were just reported by the KCNA.

The country has been defensive over allegations of human rights abuses in North Korea, though it admits not all is perfect in the country. This stance perhaps explains a recent move by Pyongyang to agree to review some of the U.N. recommendations to improve human rights in the country.
