Tehran, March 18 (RHC-Xinhua) -- Iran's Foreign Minister Mohammad-Javad Zarif said Monday that a new round of nuclear talks with the world powers scheduled for Tuesday would focus on uranium enrichment in the Persian Gulf nation.

Upon arrival in the Austrian capital Vienna Zarif told official IRNA news agency: 'The new round of talks between Iran and the P5+1 aims at reaching a comprehensive nuclear deal, the issues such as uranium enrichment inside Iran as well as Arak heavy water reactor in central Iran will be discussed.'

In this round of talks, the sides are also to discuss peaceful nuclear cooperation and removing sanctions against the Islamic republic.

However, Iran does not expect a comprehensive accord with the world powers in the Tuesday nuclear talks, Zarif said.

"For sure, this round of talks with the P5+1 group is more serious than the previous talks, but we do not expect an agreement," Zarif told reporters.

The Iranian minister reiterated that Iran will not stop any part of its nuclear program, saying that "Iran's nuclear program is a reality and this reality will not change," official IRNA news agency reported.

"We are ready to build confidence that our nuclear program will remain peaceful," the Iranian top diplomat was quoted as saying.
