North Korea has unveiled a new housing and business development in the capital Pyongyang, which it says shows its economic resilience and strength.

In recent years, the country's leader Kim Jong-un, who attended the event, has been experimenting with some economic reform, including allowing a limited number of small, private shops to exist.

John Sudworth is in Pyongyang with an invited group of foreign journalists. His movement is being tightly monitored and controlled.
