The Malaysian government plans to release a preliminary report next week on the Malaysia Airlines' missing flight, Malaysian Prime Minister Najib Razak told CNN on Thursday, more than six weeks after the flight disappeared en route to Beijing, China.

"There is a likelihood that next week we could release the report," Najib first said in the interview and then stated that the report would be released next week.

The Malaysia government has already submitted the preliminary report to the International Civil Aviation Organization (ICAO), Najib added.

The UN agency told CNN that the report, which has not been made public, includes safety recommendations for the aviation field to implement real-time tracking of commercial aircraft, the same as those recommendations made after the Air France Flight 447 disaster in 2009.

Acting Malaysian Transport Minister Hishammuddin Hussein said on Wednesday that the Malaysian cabinet had approved to establish an international investigation team to investigate the MH370 missing flight incident, which occurred on March 8 with 239 people on board the plane.

"The main purpose of the International Investigation Team is to evaluate, investigate and determine the actual cause of the incident so similar incidents could be avoided in the future," he said.

Speaking at a daily briefing on Thursday, Chinese Foreign Ministry spokesman Qin Gang said China will participate in the investigation in accordance with international conventions.

The Joint Agency Coordination Center (JACC), which oversees the search for the missing Malaysian plane, reported on Friday that Bluefin-21 Autonomous Underwater Vehicle has completed searching about 95 percent of the focused underwater area with no contacts of interest found to date.

The focused underwater search area is a circle of 10-km radius around the second Towed Pinger Locator detection which occurred on April 8.
