Mr Wilders, who heads the Freedom Party and is a member of the Dutch parliament, plans to release a short film this month which he says will depict the Koran as a 'fascist book'.

'It's really improper if he goes ahead with his plan knowing that it will hurt Muslim communities,' ministry spokesman Kristiarto Legowo told reporters.

Mr Legowo said the film would stand in the way of inter-religious dialogue essential for global stability and peace.

'Indonesia has played an active role in promoting inter-religious dialogue. (The film) will become a new obstacle,' he said.

The Dutch government has twice failed to convince Mr Wilders not to release his film, fearing a repeat of the worldwide protests which met the publication of satirical Danish cartoons of the prophet Mohammed.

Indonesia, a former Dutch colony, is the world's most populous Muslim nation, where most Muslims practise a tolerant strain of the religion.

Criticism of Islam is a charged issue in the Netherlands, which is home to a sizeable minority of Muslim migrants.
