US President George W. Bush called on Tuesday for "no expansion" of Israeli settlements in Palestinian territories just days ahead of his meeting with Israeli Prime Minister Ariel Sharon.

"Our position is very clear, that the roadmap is important, and the roadmap calls for no expansion of the settlements," Bush told the media.

"I'm optimistic that we can achieve a peace in the holy land. I 'm optimistic because I firmly believe that Ariel Sharon wants to have a peaceful partner, wants there to be a democracy in the Palestinian territories," said Bush.

"I look forward to meeting the prime minister in Crawford to continue to work with the parties to advance peace," Bush said.

Bush is to welcome Sharon next Monday in his Texas ranch and the issue of settlements will surely come up in their talks.
