He expressed hope that the fire will be completely extinguished on Friday, adding all the available resources are mobilized to put the fire out so that the fate of the tanker’s 30 missing crew will be determined.
He underlined the instruction of Li Keqiang, Premier of the State Council of the People's Republic of China, saying the Chinese official issued significant instructions for taking the required action to save the missing tanker crew.
