Iran and the European Union (EU) will begin “all-out cooperation” in different arenas, Iranian Foreign Minister Mohammad Javad Zarif said before talks with the EU's foreign policy chief Federica Mogherini in Brussels.

"Iran and the European Union are ready to start comprehensive cooperation," TASS cited him as saying.

The minister noted that the agenda of the talks will be very broad: It will include the process of implementation of the agreement on the Iranian nuclear program, as well as the resolution of the crises in Syria and Yemen.

He added that high-level talks between the two sides have already begun and that they will continue at the ministerial level in the upcoming trip to Iran by Mogherini, Press TV reported.

Zarif said a significant breakthrough has been made on the implementation of the nuclear agreement between Iran and the P5+1 group.

Zarif met with Janusz Lewandowski, chairman of the European Parliament’s delegation for relations with Iran, and discussed Iran-EU cooperation.

During his two-day visit, the Iranian foreign minister also is expected to sit down with Belgium Prime Minister Charles Michel as well as a number of other EU officials, including the EU foreign policy chief, European Parliament President Martin Schulz and European Council President Donald Tusk.

‘A propaganda slogan’

Zarif dismissed as “propaganda” claims by certain regional countries that they might deploy troops to Syria, saying no outsider can make decisions for the conflict-stricken country, Press TV reported.

“It is obvious that these remarks are more of a propaganda slogan. The means and capabilities of countries are completely clear and with these propagandist bluffs, none of their problems will get resolved,” Zarif said upon his arrival in Brussels early on Monday to discuss key regional issues with European Union officials.

However, such claims will further escalate tensions in the Middle East region, Zarif warned.

The top Iranian diplomat called on the neighboring countries to see the realities on the ground, “set aside illusions,” and stop imposing their will on the Syrian people.

It is up to the Syrian people to decide their future, he said.

Zarif’s comments came as Saudi Arabia and Turkey have in recent weeks raised the possibility of launching ground operations inside Syria.

Bahrain and the United Arab Emirates (UAE) also followed in Saudi Arabia's footsteps and hinted their preparedness for similar deployments.

Swiftly welcomed by the United States, the proposal was met with strong criticism from Syria and its allies.

Damascus has issued warnings against any such move with Foreign Minister Walid al-Muallem saying that any “ground intervention on Syrian territory without government authorization would amount to an aggression that must be resisted.” He has also warned that potential aggressors would return home in a “wooden coffin.”

The development comes as Syrian troops, backed by Russian air raids, have been making gains against foreign-backed terrorists.

For nearly five years, Syria has been grappling with a foreign-backed militancy. According to a new report by the Syrian Center for Policy Research, the conflict has claimed the lives of some 470,000 people, injured 1.9 million others, and displaced nearly half of the country’s prewar population of about 23 million.
