The United Nations Security Council will soon consider Australia's resolution demanding that pro-Russian separatists provide "full and unrestricted access" to the crash site of a downed jet in Ukraine.
A vote is set for Monday at 3pm in New York which is 5am Tuesday AEST.
The document, proposed by Australia and co-sponsored by countries like France, also calls on all actors in the region to fully co-operate in an international probe of the incident.
It demands that all military activities, including by armed groups, be "immediately ceased in the immediate area surrounding the crash site to allow for security and safety of the international investigation".
Russia, as a permanent member of the Security Council, has the right to exercise its veto power to scrap the resolution.

Malaysia Airlines flight MH17 is believed to have been blown out of the sky on Thursday by a surface-to-air missile, killing all 298 passengers and crew. Among the dead are 37 Australian citizens and residents.
The measure "condemns in the strongest terms" the actions that caused the plane to crash.
It demands that armed groups controlling the area "refrain from any actions that may compromise the integrity of the crash site ... and immediately provide safe, secure, full and unrestricted access to the site and surrounding area for the appropriate investigating authorities".
While not mentioning Russia specifically, it "calls on all states and actors in the region to co-operate fully in relation to the international investigation of the incident".
The text also urges countries to respect international civil aviation safety rules "in order to prevent the recurrence of such incidents, and demands that all states and other actors refrain from acts of violence directed against civilian aircraft".
World leaders have demanded Russian President Vladimir Putin use his influence to persuade the rebels to hand over the victims and allow full access to the crash site.
Major European nations have warned Moscow of additional possible sanctions over the crash.
