Iranian Foreign Minister Mohammad Javad Zarif said on Wednesday that he is confident that a lasting agreement can be struck with world powers over his country's nuclear program.

"I am confident that a comprehensive agreement is imminently within reach," Zarif wrote in a letter published by his ministry.

"It requires foresight, political will and recognition of realities by our negotiating partners as well as the audacity to make the right choice benefitting the entire global community," Zarif said.

Zarif asserted that Iran rejected "arbitrary, degrading and unlawful demands" made by other countries over its enrichment of uranium.
