(Bloomberg) -- The search for Malaysia Airlines Flight 370 is in peril once again as new Prime Minister Mahathir Mohamad reins in government spending.

The contract to find the jet, missing since 2014, is under review, Mahathir said after his first cabinet meeting on Wednesday. The government in January agreed to pay U.S. exploration company Ocean Infinity as much as $70 million if it solves what has become modern aviation’s biggest mystery.

"We want to know what is the necessity for this, and if we find that it is not necessary, we will not renew," Mahathir, who returned to power in a shock election triumph this month, told reporters in Putrajaya. “We may terminate it if it’s not useful."

Ocean Infinity’s search vessel, Seabed Constructor, has already scoured 86,000 square kilometers of seabed in the southern Indian Ocean without success, according to the latest weekly report on the operation. That area includes the patch that investigators identified as the aircraft’s most likely resting place before the search was abandoned in 2017.

A representative for Ocean Infinity was unable to immediately comment when reached by email.

The Boeing Co. 777 aircraft disappeared on March 8, 2014, on its way to Beijing from Kuala Lumpur with 239 people on board. Investigators tracked MH370’s route using satellite data and believe the plane headed south over the Indian Ocean for about six hours before plummeting into the water.
