KUALA LUMPUR, Malaysia — Malaysia's transport minister said Sunday that the government is open to new proposals from U.S. technology firm Ocean Infinity or any other companies to resume the hunt for Flight 370, as families of passengers marked the fifth anniversary of the jet's mysterious disappearance.
But the company's CEO, Oliver Plunkett, said in a video shown at the public remembrance event at a mall near Kuala Lumpur that the company hopes to resume the hunt with better technology it obtained in the past year.
"We haven't given up hope. ... We hope we can continue the search in due course," Plunkett said.

Transport Minister Anthony Loke said it's been frustrating that the two searches failed to produce any clues and that he "welcomes credible leads and also concrete proposals to resume the search."
He told reporters later Sunday that the government is "waiting for specific proposals, in particular from Ocean Infinity." He brushed off suggestions of offering rewards to find the plane, but said the government is willing to discuss proposals from any companies prepared to resume the search.
"There must be a proposal from a specific company ... we cannot just be out there without credible leads. That's the most practical thing to do," Loke said.
The plane vanished with 239 people on board on March 8, 2014, while flying from Kuala Lumpur to Beijing. Confirmed debris that washed ashore in the western Indian Ocean helped narrow the search area where Ocean Infinity focused, but it failed to uncover any evidence.
Investigators, however, said the cause of the disappearance cannot be determined until the wreckage and the plane's black boxes are found. The report reiterated Malaysia's assertion that the plane was deliberately diverted and flown for over seven hours after severing communications.
But it said there was no evidence of abnormal behavior or stress in the two pilots that could lead them to hijack the plane. All the other passengers were also cleared by police and had no pilot training.
Voice 370, a support group for next-of-kin, expressed hope that the new government that won a general election in May last year will do more to encourage search missions and seek new clues.
The group's spokeswoman, Grace Nathan, urged the government to set aside up to $70 million — the amount it agreed to pay Ocean Infinity had it found the plane — to encourage exploration companies to take on "no cure, no fee" missions so that Flight 370's passengers will not have died in vain.
"It is a wound that cannot heal" if there is no closure, Nathan said.
During the remembrance event, family members lit candles and sang songs in tribute to their loved ones.
Relatives and supporters wore light blue T-shirts that read, "It's not history, it's the future. Fly safely," as they reminded the government that the mystery must be solved to ensure aviation safety.
