Thank you, Mr. Chair.
I want to go back to the question of Ukraine's arms exports. We know that President Poroshenko announced in 2015 that he wanted to make Ukraine one of the top five arms exporters in the world. In 2016 they achieved I think it was 11th position. Certainly, when you look at who they sell arms to, it's not always countries that would be high on the human rights list, like Ethiopia, Nigeria, Uganda. In fact, it appears that the largest amount of Ukrainian military goods are actually continuing to go to Russia through third party deals, despite the official boycott of sales to Russia.
I'm going to ask Ambassador Mason, with the largest experience in disarmament, again, about the question of end use. If the decision were made to sell lethal weapons to Ukraine, what guarantees do we have that these would not be exported or their substitutes exported to other countries around the world?
