Russia is pushing for a greater United Nations role in an investigation into what caused the downing of Malaysia Airlines flight MH17 after dismissing a proposal by Malaysia, Australia, the Netherlands, Belgium and Ukraine for a UN-backed tribunal.
Led by the Dutch, the countries are conducting a criminal inquiry into MH17 and circulated a draft resolution to the UN Security Council earlier this month that would create a tribunal to prosecute those responsible.
But Russian President Vladimir Putin has described the move as counterproductive and premature. Russia is a Security Council veto power and therefore could block the bid if it is put to a vote.
Russia has instead circulated its own draft UN resolution that would "demand that the perpetrators of the aerial incident be brought to justice." The 15-member council discussed the draft resolutions on Monday.
New Zealand Ambassador Gerard van Bohemen, president of the council for July, said it was a "very positive discussion", but noted that the key hurdle was the issue of a tribunal.
"There was strong support in the room for the establishment of a tribunal. Russia of course has a different perspective on this," he told reporters.
Russian UN Ambassador Vitaly Churkin said earlier that Moscow was opposed to an international tribunal because "we believe it's not in the UN Charter, the UN Security Council is not supposed to deal with situations like that."
When asked if Russia was against the tribunal proposal, Churkin said: "Yes." Earlier this month he described the proposal as an attempt to organise a "grandiose, political show."
A final report on the cause of the MH17 crash, separate to the criminal investigation, is due in October from the Dutch Safety Board.
Ukraine and Western countries accuse the rebels of shooting down the plane with a Russian-made missile, but Moscow has rejected accusations it supplied the rebels with SA-11 Buk anti-aircraft missile systems.
The Russian UN draft would request UN Secretary-General Ban Ki-moon to report to the council within two weeks on "the steps that would enhance the role of the United Nations in support of the (safety) investigation" and the appointment of a UN special envoy on the incident.
It also expresses concern that the ongoing safety investigation has been delayed and "does not ensure due transparency in its organisation and work methods, which may have a negative impact on its outcome."
British UN Ambassador Matthew Rycroft, also a council veto power, said on Monday: "We don't support the Russian draft."
Malaysia, Australia, the Netherlands, Belgium and Ukraine rejected the accusations in the Russian draft, saying that both the safety and criminal investigations were being carried out in line with the highest international standards.
The Russian draft resolution asks for those countries to "keep the council fully and regularly informed on the progress" of the criminal investigation. But in a joint statement they said the criminal investigation would remain confidential so any future prosecutions would not be jeopardised.
"It is important for the Security Council to take clear and decisive action against those responsible for the downing of MH17 to send a clear message to the growing number of non-State actors with the ability to target civilian aircraft that such attacks will not be tolerated," the statement said.
Those countries hope to put their draft resolution to a vote this month, diplomats said.
