Penang Chief Minister Lim Guan Eng has accused the Malaysian Anti-Corruption Commission (MACC) of singling out Penang for refusing to sign the commission's anti-corruption pledge.

Lim said that there were other states which have refused to do so, but MACC head Dzulkifli Ahmad had repeatedly criticised the Penang government only.

"He does not mention those states. He keeps targeting Penang. Why is he doing this?" asked Lim when met by reporters today.

Lim was responding to Dzulkifli's remarks yesterday, in which he claimed that other states had signed the pledge on their own initiative.

"What's so special about Penang? Other states voluntarily signed it. I don't know why (chief minister) Lim Guan Eng said he needs to be invited.

"The other states even contacted us about signing the pledge. So why does Penang need to be invited?" he said, adding that the pledge would present the respective state government's commitment towards fighting graft.

While dismissing Dzulkifli's claims, Lim said his administration would sign the pledge if the MACC includes 10 of the state government's recommendations, which includes the declaration of assets by the state cabinet members.

Although Lim does not agree with MACC's pledge, he said he would be consulting his state exco members on what to do next when they meet this Friday.

He said the war against corruption was not just about signing pledges but having the political will to do something about it.

"Is the MACC targeting us because we are performing well, we have reduced our debts, we practise the open tender system and have budget surpluses.

"We have been praise by the Auditor-General's Office and Penang is the only state which had been praised by Transparency International," he added.
