BEIJING - Micro blogs have brought new challenges for government as it responds to emergencies and fights to gain the upper hand in solving social problems, experts said.

"Micro blogs have virtually created a competitive relationship between the government and the public for dominance after some public events happen," said Wu Hui, a professor at the Party School of the Communist Party of China Central Committee.

Wu said the faster the government responds, the higher the possibility that it will win public understanding and support, and the chances for rumors will be reduced.
