Iranian Foreign Ministry Spokesman Ramin Mehmanparast says Tehran will defend its nuclear rights and will not retreat one iota from its stance in the upcoming talks with the P5+1, Press TV reported.
Mehmanparast said Western officials visiting regional states ahead of the second round of talks between Iran and the P5+1 -- Britain, China, France, Russia, and the US plus Germany-- in the Iraqi capital are psychological war tactics to pressure Tehran.
"Such issues will have no effect on the resolve and demands of the Iranian nation and their representatives [in the upcoming Baghdad talks]," Mehmanparast told IRNA.
"Respecting the rights of other nations must be a principle and by eliminating injustice many tensions can be defused," he added.
Mehmanparast stressed Iran is determined to see a just world order and would spare no effort to see this goal materialize.
The latest round of talks between Iran and the five members of the P5+1 group was held in the Turkish city of Istanbul on April 14. Both sides hailed the discussions as constructive.
The two sides agreed to hold the next round of talks in Baghdad on May 23, 2012.
Tehran and the P5+1 previously held two rounds of talks, one in Geneva, Switzerland in December 2010 and another in Istanbul in January 2011.
