However, the Ukrainian government had informed the investigation team that the crash site was under the full control of separatist groups and "it cannot guarantee the safety of the international team in and around the crash site", Xinhua quoted Malaysia's Transport Minister Liow Tiong Lai as saying in Kiev on Sunday.
The situation was further hampered by reports that a number of competing separatist groups control the area in and around the crash site, with no clear leader or chain of command, he said.

Malaysia was deeply concerned about this situation and demanded immediate and unrestricted access to the crash site and safety guarantee for international investigators and search and recovery personnel.
The Malaysia Airlines MH17 flight with 298 people on board crashed on Thursday in eastern Ukraine, with no survivors found so far, making one of the worst tragedies in the history of civil aviation.
"Malaysia demands that all human remains must be allowed to be recovered, identified and repatriated," the minister said in Kiev.
A Malaysian team of 133 officials and experts, comprising search and recovery personnel, forensics experts, technical and medical experts arrived in Kiev on Saturday morning.
