Obama no better than Bush -Iran parliament speaker

* Iran speaker denounces Obama's "baseless slogans"

* Comes after U.S. renewed some sanctions, skyscraper move

* Criticises "irrational" U.S. nuclear proposals

TEHRAN, Nov 15 (Reuters) - U.S. steps to renew sanctions and seize a New York skyscraper linked to Iran show that President Barack Obama is no better than his predecessor George W. Bush, Iranian parliament speaker Ali Larijani said on Sunday.

Larijani's statement, which was followed by chants of "Death to America" among MPs in the legislature, was the latest from Tehran voicing disappointment in the new U.S. administration's policies towards the Islamic Republic.

It came as Obama, during a visit to Asia on Sunday, said time was running out for diplomacy in a dispute over Iran's nuclear programme, which Tehran says is for peaceful purposes but which the West suspects has military aims.

Since taking office in January, Obama has sought to reach out diplomatically to Iran, but the dispute over Tehran's atomic activities continues.

"After one year of giving speeches and baseless slogans, it is a disgrace to see the behaviour and the attitudes of this president are not better than his predecessor's," Larijani told parliament, the official IRNA news agency said.
