India is committed to buying Iranian oil and continuing the two nations' economic cooperation, the Iranian foreign minister said after a meeting with his Indian counterpart and ahead of US sanctions aimed at halting Tehran's oil exports.

US President Donald Trump's May withdrawal from an international nuclear pact with Iran was followed up with plans to impose new sanctions against the third-largest producer among the Organisation of the Petroleum Exporting Countries (OPEC).

Washington is pushing allies to cut Iranian oil imports to zero once the sanctions start on November 4.

Iran's Foreign Affairs Minister Mohammad Javad Zarif met his Indian counterpart, Sushma Swaraj, in New York on the sidelines of United Nations General Assembly, according to a video from news agency ANI, a Reuters affiliate.

"Our Indian friends have always been categorical in terms of their intention to continue economic cooperation and (the) import of oil from Iran. And I heard the same statement from my Indian counterpart," Zarif said when asked if India has given an assurance about continuing with oil imports.

India, Iran's second-biggest oil client behind China, has already reduced its intake of Iranian oil but has not yet decided whether to end purchases completely.

"We have comprehensive cooperation with India and that comprehensive cooperation also includes energy cooperation because Iran has always been a reliable source of energy for India," Zarif added.

Iran is India's third-biggest oil supplier and the South Asian nation had drawn plans to increase purchases this financial year after Tehran offered almost free shipping and extended credit period.

In the previous round of sanctions, India was one of the few countries that continued to trade with Iran.

Zarif said Iran wants to expand its bilateral relations with India.

The Indian-backed Chabahar port complex in Iran is being developed as part of a new transportation corridor for land-locked Afghanistan. The complex could open the way for millions of dollars in trade and cut India's dependence on neighbour Pakistan.

The plant is expected to be operational by 2019.

India is looking at providing a $3.5 million-equivalent bank guarantee for development of the port through UCO Bank, another government source said.

Zarif said that Chabahar is still functional and Iran wants to expand its capacity with support from Indian and other investors.
