It also says sanctions will end when the board of IAEA confirms that Iran has complied with all its obligations.
Earlier yesterday, Iran's top nuclear negotiator, Ali Larijani, said the resolution made his country more "decisive in realizing our nuclear aims."
"From Sunday morning, we will begin activities at Natanz -- site of 3,000-centrifuge machines -- and we will drive it with full speed. It will be our immediate response to the resolution," Iran's Kayhan newspaper quoted Larijani as saying.
Iran showed its ability to enrich uranium in February, when it produced a small batch of low-enriched uranium using a set of 164 centrifuges at its pilot complex in Natanz.
