"Imposing sanctions and adopting a resolution will as a result prompt a reaction from Iran, and in this case we will revise our cooperation with the agency," foreign ministry spokesman Mohammad Ali Hosseini told reporters.

Hosseini did not specify what cooperation with the International Atomic Energy Agency (IAEA) could be hit, but such a move would most likely restrict UN inspections of Iran's atomic facilities.

"Our decision will depend on the decision" of the five permanent Security Council members plus Germany, which have been examining Iran's nuclear case.

Hosseini said Russia was seeking to tone down the text of the draft resolution, which he said bore the marks of the "interventionist policies of the United States".

He criticised the three major European powers for "choosing a wrong path... I hope they will change their policy and return to a policy of negotiation."

The six major powers were to resume talks in New York on Monday on proposed targeted UN sanctions against Tehran over its refusal to halt uranium enrichment.

The sanctions would bar trade with Iran in goods related to its ballistic missile programme and nuclear industry, and impose financial and travel restrictions on people and entities involved.

The six powers have been trying to thrash out agreement on the text for weeks, with Russia and China -- which have strong economic interests in Iran -- seeking to water down the European-proposed draft.

Iran vehemently rejects US charges that it is seeking to make a nuclear weapon, saying it has every right to the full nuclear fuel cycle in order to supply civilian energy.
