ARSENIY YATSENYUK:

Absolutely, when Ukraine relinquished its nuclear weapon. And, at that time, we possessed the third biggest nuclear arsenal in the world.

And they were given towards the U.S., the U.K., and Russia that signed the Budapest treaty and guaranteed Ukrainian independence. One of these key signatories, Russia, have violated the deal.

And so today, we need not just the statements, not just the declarations. But we ask our partners to undertake real steps in order to support Ukrainian independence. And independence and military strength is so tightly correlated in this world.

I'm not sure I can dwell into details on this particular issue, but we have started a dialogue with our American partners and with the U.K. government how to support Ukraine to defend its independence.
