US secretary of state and British foreign secretary and Ukrainian interim foreign minister, on Thursday, urged Russia to honour the 1994 Budapest Memorandum.
The three officials, John Kerry, William Hague and Andriy Deshchytsia, made the call in a joint statement while meeting in Paris.
They noted that “the Budapest Memorandum sets out the obligations of signatories in return for Ukraine giving up its nuclear weapons.
“The memorandum also obliges the UK, US and Russia to consult in the event of a situation arising where the memorandum commitments are questioned.”
The statement added that the US had conveyed an invitation to Russian Foreign Minister, Sergey Lavrov, but he did not attend the meeting.
