The missing Malaysia Airlines flight will not overshadow relations between Beijing and Kuala Lumpur, leaders of the two countries have declared through a series of high-profile events marking the 40th anniversary of diplomatic ties.
Premier Li Keqiang told visiting Malaysian Prime Minister Najib Razak on Thursday, "Chinese people say that at the age of 40 one should no longer have any doubts.
"Your visit at this important moment, the 40th anniversary of our diplomatic relations, embodies a lot of significance."
Analysts said both countries were consolidating their ties and seeking stronger support from each other as China tackled simmering tensions in the South China Sea and with Malaysia poised to chair the Association of Southeast Asian Nations next year.
Najib, who began a six-day visit to China on Tuesday, met with Li on Thursday after visiting Xi'an, the capital of Shaanxi province.
During their closed-door meeting, which lasted for more than 90 minutes, Li urged Malaysia to formulate a new working plan in the search for flight MH370.
Earlier on Thursday, Australia said the area where acoustic signals thought to be linked to the Malaysian plane were detected could now be ruled out as its final resting place, Reuters reported.
The Boeing 777-200 disappeared on March 8 on a flight from Kuala Lumpur to Beijing. Of the 239 people onboard, 154 were Chinese.
Li said China had not halted the search for the plane and was paying great attention to this and related issues.
He urged Malaysia to continue its leading and coordinating role in the search, to continue to investigate the incident, comfort passengers' relatives and heed their "reasonable" appeals.
