(CNN) Iran is enriching more uranium per day now than before the country signed a nuclear deal with major world powers, President Hassan Rouhani said Thursday.

Rouhani also said the country's nuclear industry was better off today during his address at the 59th Iranian Central Bank General Assembly in Tehran that was broadcast live on Iranian state television.

"Our daily enrichment is today more than before signing the (JCPOA) agreement," Rouhani said, referring to the Joint Comprehensive Plan of Action, the official name of the 2015 nuclear deal. Rouhani offered no specifics on how much more uranium is now being enriched.

Signed by Iran and the US, France, Russia, China and Germany -- a group known as the P5+1 -- after two years of intense negotiations, the deal was intended to limit Iran's civilian nuclear program and prevent it from developing nuclear weapons in exchange for sanctions relief.

But the deal began to unravel when the US walked away from it in 2018 and reimposed sanctions on Iran. Tehran has responded in recent months by pulling back from some of its commitments under the pact.
