"We are not going to take away these boxes, nor to violate the rules with regard to this sort of cases within the international community," Xinhua quoted the Russian foreign minister as saying in an interview.
"This is the sphere of activity for the International Civil Aviation Organisation (ICAO), for the countries that are directly involved: the Netherlands, Malaysia and the ones whose nationals were on board, as well as Ukraine, of course," he said.
There is still no official confirmation on whether the flight recorders have been found or not, nor about their possible whereabouts.
Russia: We are not going to take away these boxes
The Interstate Aviation Committee (IAC) said Friday the flight recorders, once found, should be handed over to the international investigative commission organised under the aegis of the ICAO.
A Malaysian flight with 283 passengers and 15 crew members on board crashed on Thursday in Ukraine near the Russian border.
US officials told media that they concluded the plane was shot down by a surface-to-air missile. Investigations are under way to figure out what happened to the plane.
US President Barack Obama and Ukrainian President Petro Poroshenko stressed during their phone conversation Thursday that evidence from the crash of Malaysian airliner must stay in Ukraine before it is investigated.
