Chief Minister Datuk Seri Musa Aman said Sabah's doors are always open to those who want to see and embrace its ethnic and cultural diversities, as well as participate in the state's festivities.

He said Sabah also welcomed those who respected a civil society, whereby there was law and order to uphold the prevailing peace and harmony.

"However, if we have reason to believe that your presence here will pose a threat to these ideals that Sabah has enjoyed all this while, you are not welcome here," he said in a statement here on Saturday.

Musa said contrary to what was being spread in the social media, the ban on PKR vice-president Nurul Izzah Anwar from entering the state was not politically motivated.

"Other opposition leaders have come and moved freely throughout Sabah, especially during the run-up to the elections. They spread the same old recipe of lies, deceit and slander to hoodwink the people. We didn't stop them," he said.

"Now that the elections are over, their leader refuses to accept the verdict. It is a case of sour grapes and ungentlemanly conduct. He wants to rile up the masses to rally throughout the country to show his, and I repeat, his discontent," he said.

"We have reason to believe that Nurul Izzah's intentions to come to Sabah, this time around, may not be as innocent as she or her fellow opposition members make it out to be," he added.

She was barred from entering the state on Thursday.

Musa said Sabah and its people did not need the endless propaganda by the opposition to incite hatred and mistrust among the people against the Barisan Nasional government.

"Enough is enough. We need to move on. The opposition has been politicking for the last five years. Are we going to get bogged down by more politicking in the next five?

"There's work to be done. The country needs to be administered, the economy needs to grow and the people's welfare, taken care of," he said.
