Nations involved in the search for the Malaysia Airlines jetliner that disappeared on Saturday must do a better job of sharing information and coordinating rescue efforts, Chinese experts said.

"Currently, there are no international conventions governing information-sharing and cooperation among countries in the search and rescue of ill-fated aircraft," Wang Ya'nan, an aviation expert in Beijing, told China Daily on Wednesday.

"The country that owns the airliner involved in an accident must take the responsibility of providing timely and accurate information to other nations and properly coordinating search efforts."
