The Communist Party secretary of CAO parent China Aviation Oil Holding (CAOH), Hai Liancheng, told Xinhua its Singaporean subsidiary was operating 'normally' and the scandal would not disrupt aviation fuel supplies. 'The debt of the Singapore company will not affect CAOH. However, the Singapore company is an important subsidiary of CAOH and a key platform and window of CAOH's overseas expansion. If it goes bankrupt, it will tarnish the international image of Chinese companies. The negative impact should not be underestimated,' he said.
