Iran's envoy to the UN nuclear watchdog has been quoted as saying Tehran will never give up its controversial uranium enrichment program "at any price."
In an interview with Britain's "New Statesman" magazine, Ali Asghar Soltanieh said the West must get used to an Iran that is a "master of enrichment."
Soltanieh said threats of fresh UN sanctions -- led by the United States -- reflected a "colonialist mentality."
Soltanieh said U.S. President Barack Obama had come to power with a slogan for change, but, so far, had been "unable to deliver."
"New Statesman" said the interview was conducted in Vienna "one recent Sunday" but did not give the date.
This month, Tehran announced plans to further enrich uranium for a reactor making isotopes for cancer research, raising fresh concerns in the West.
Western powers had proposed Iran send abroad much of its low-grade uranium in exchange for fuel rods for the medical reactor.
