I thank the noble Lord for, as ever, his very insightful and forensic question. It is perfectly clear that the global community, as reflected by the United Nations and particularly its Security Council, believes that the correct approach to this is a mixture of diplomatic and economic measures. Going back to what I detected was some scepticism about the effect of the sanctions, perhaps I might quote from what the UK Permanent Representative to the United Nations, Matthew Rycroft, said yesterday. He said that it is clear that these sanctions,
“are having an effect … Those who doubt this impact need only read the statements coming from the North Korean regime”.
The measures to date are having an effect. As the noble Lord is aware, the UK Government are currently in discussion with our global partners as to what further steps we might take, but there is evidence that North Korea is beginning to feel the tourniquet of these sanctions.
