In a televised speech, Presideyy彩票nt Hassan Rouhani also said that Iran would stop exporting extra uranium and heavy water from its nuclear program. The export of heavy water and extra uranium were requirements of the deal.
Enriched uranium can be used to make nuclearyy彩票 weapons. Heavy water is used to cool nuclear reactors.
Rouhani did not explain how much uranium it would enrich.
One year ago, U.S. President Donald Trump withdrew from the agreement. China, Russia and European nations are still part of the deal, however.
After the United States withdrew from the deal, it put syy彩票trong sanctions on Iran. The move caused a severe economic crisis.
Rouhani said Iran wanted to negotiate new terms for the deal with remaining partners. He wants new terms to permit Iran to sell its oil, which it currently cannot do because of the U.S. sanctions.
Rouhani also warned of a "strong reaction" if European leaders try to put more sanctions on Iran through the U.N. Security Council. He did not explain what a "strong reaction" might be.
Rouhani also said that Iran wants action within 60 days. If there is no action, Iran will stop a Chinese-led effort to redesign its Arak heavy water nuclear reactor. Such reactors produce plutonium, which can be used in nuclear weapons.
U. S. Secretary of State Mike Pompeo on Wednesday was meeting with British Prime Minister Theresa May and Foreign Minister Jeremy Hunt for talks before Trump's visit to Britain next month. Pompeo told reporters the United States would decide how to answer Iran after Iran takes action.
美国国务卿蓬佩奥周三与英国首相特蕾莎·梅（Theresa May）和外交部长杰里米·亨特（Jeremy Hunt）进行了会谈，下个月川普将会访问英国。蓬佩奥对记者表示，美国将会在伊朗采取行动后再决定如何做出回应。
Hunt said on Wednesday the agreement remained an important achievement and urged Tehran to think before breaking it. He said Britain and the United States agreed that Iran should never be permitted to have a nuclear weapon.
Russian Foreign Minister Sergei Lavrov welcomed Tehran's Foreign Minister Javad Zarif for talks on Wednesday in Moscow. Following the meeting, both countries condemned the United States for leaving the deal a year ago, a move they say caused the current problems.
俄罗斯外长谢尔盖·拉夫罗夫(Sergei Lavrov)周三在莫斯科迎来了伊朗外长贾瓦德·扎里夫（Javad Zarif），并与之进行了会谈。会谈结束后，两国都谴责美国在一年前退出该协议，他们称正是此举引发了目前的问题。
Zaryy彩票if gave his own warning from Moscow.
"After a year of patience, Iran stops measures that (the) US has made impossible to continue," he wrote on Twitter.
The 2015 nuclear deal lifted economic sanctions on Iran in exchange for limits on its nuclear program. Iran reached the deal after years of negotiations that included secret talks in Oman between Iran and the administration of former U.S. President Barack Obama.
Western governments had long feared Iran's nuclear program could lead to the development of nuclear weapons. Iran has always said its nuclear program is for peaceful purposes.
The United States left the deal after Trump campaigned on a promise to end the agreement. His administration says the deal should have put limits on Iran's ballistic missile program. It also believes the deal did nothing to end Tehran's efforts to influence Iraq and other countries in the area.
There is still hope for the deal. Iran did not walk away from it, but instead chose to stop exporting its extra uranium and heavy water. Observers say that means there is still the possibility for an agreement to be reached.
Under the 2015 deal, Iran cannot keep more than 300 kilograms of low-enriched uranium and 130 tons of heavy water. By comparison, the country used to possess 10,000 kilograms of higher-enriched uranium.
