A Chinese family member to one of the missing flight MH370’s passengers collapsed yesterday after having had to wait long hours to meet Transport Ministry Liow Tiong Lai.

The family members from China were seeking to meet Liow for a proper explanation on the missing flight.

Wen Wan Cheng, 65, who waited for Liow since 9am with 17 others, began to feel dizzy and collapsed, said another passenger’s family member Li Hwa.

"My friend is a diabetes patient and had suffered a heart attack before. He collapsed following hours of empty stomach and hot weather," he said, adding that Wen later felt better after taking medication.

"Despite this, he refused to go to hospital for he feared missing the opportunity to meet the minister," said Li, a 59-year-old father who lost his daughter on the flight.

The group has vowed to "campaign days and nights" until they have met Liow.

They also planned to secure dialogues with various department heads from Bukit Aman, Transport Ministry and the Department of Civil Aviation, he said.

"Since most of us are elderly and above 60 years old, we can only come back and wait during the day time," he said, adding they left Putrajaya at around 9pm last night.

The families had arrived in Malaysia on Feb 12 and have since been trying their luck with Malaysia Airlines, Prime Minister's Department, MCA and Bukit Aman to seek help.

‘Letter from MAS is newspaper article’

Li Hwa also said that the letter issued by MAS earlier was a "plagiarised copy" from the newspaper and online reports as the contents were highly identical.

"With this, we submitted another letter and (the ministry) said they will reply to us in three days, but we have already waited for five days," he said.

The letter dated Feb 25, questioned the government’s presumption that the passengers on board had died over the accident.

It also criticised the airlines for ignoring to the needs of the families members.

The Beijing-bound plane went missing with 239 passengers and crew aboard after taking off from Kuala Lumpur International Airport on March 8, 2014.

It was reported that Australian Deputy Prime Minister Warren Truss saying that Australia and China will discuss and decide when to stop the search as it cannot go on forever.

To cease the search operation in the Indian Ocean is not unacceptable to the families, said Li.

"Of course we disagree, we will take action to prevent this from happening. Both Australia and Malaysia have promised they will not give up the search. So, how do you want the world to look at you (if you break your promises)?" he asked.
