Chinese joint working group paid two respective visits to the family members of Chinese passengers on the missing MH370 flight on Saturday and Wednesday.

Guo Shaochun, head of the Chinese task force, said that two weeks have passed since flight MH370 went missing and they were as anxious as the family members of the passengers on board.

He said that the Chinese government had been paying great attention to the incident since the search and rescue operation entered a new phrase.

During his phone conversation with Australian Prime Minister Tony Abbott, Chinese President Xi Jinping said as long as there was a glimmer of hope, they needed to give 100 percent of their efforts, Guo said, adding that Chinese Premier Li Keqiang also made a second phone call to his Malaysian counterpart Najib Razak.

Guo said China deployed its ships and aircraft including the country's Ice Breaker Xue Long to carry out search and rescue work in related sea areas.

Dozens of countries have joined in the mission at the request of China, Guo said, adding that they would continue urging the Malaysian side to carry on the investigation at the same time.

According to Guo, the Chinese government has been attaching great importance to coordinating with Malaysia on taking good care of and helping the family members, and the Malaysian authorities said they would always be responsible. "Please be at ease and take good care of yourselves, whether staying in Malaysia or leaving the country, your choice will be respected,"he said.

The family members said their major concern is to find their beloved ones, and hoped that Malaysia could keep them posted about any findings and intensify search and investigation efforts.
