Ukraine should already have closed air space over a conflict area where MH17 came down in July last year, a report into the disaster is expected to say.
The International Civil Aviation Organisation is also looking into new regulations on war-zone flying in the wake of the disaster, ITV News understands.
A Russian manufacturer has refuted claims that its Buk missiles were the cause of the MH17 air disaster.
ITV News understands that a report released by Dutch investigators will say that a warhead typically associated with the missile system hit the plane, causing it to come down over eastern Ukraine in July last year.
However, in a press conference shortly before the report's release, the Almaz-Antey manufacturer insisted its own results "completely disprove" such a conclusion.
Citing an "experiment" carried out by the state-controlled company, general director Yan Novikov claimed that if the plane was indeed shot down by a missile, it would have come from the Zaroshenske, a village Russia says was under the control of the Ukrainian government at the time.
A report into the MH17 air crash will show that the plane was hit by a warhead of the type used on a Buk missile system, ITV News understands.
It is understood that the report by Dutch investigators will also show the missile hit above and to the left side of the cockpit, and those on board did not feel anything on its impact.
Buk missiles are developed in Russia, and have allegedly been used by pro-Russian rebels in eastern Ukraine, where the plane came down.
The missile's manufacturer has already challenged investigators' view of events leading to the disaster.
The final report into what caused flight MH17 to crash will be published today.
