Iran has vowed to respond to a resolution adopted by the United Nations' nuclear watchdog that criticizes the Islamic republic for what it says is poor cooperation by installing a number of "new and advanced" centrifuges.
The resolution, which comes shortly after the return of International Atomic Energy Agency (IAEA) chief Rafael Grossi from a trip to Iran, reportedly says it is "essential and urgent" for Tehran to "act to fulfill its legal obligations."
A joint statement by Iran's Foreign Ministry and Atomic Energy Organization said on November 22 that the country's nuclear chief, Mohammad Eslami, "issued an order to take effective measures, including launching a significant series of new and advanced centrifuges of various types."
The Iranian announcement came after the IAEA's board on November 21 issued a second resolution condemning Tehran's cooperation with the agency after a similar warning in June.
Some analysts say the resolution may be a step toward making a political decision to trigger a "snapback" of UN Security Council (UNSC) sanctions against Iran.
The "snapback" mechanism is outlined in UNSC Resolution 2231, which enshrined a 2015 nuclear deal between Iran and world powers. However, the option to reimpose the sanctions expires in October 2025.
The IAEA resolution, put forward by France, Germany, and Britain and supported by the United States, comes at a critical time as President-elect Donald Trump prepares to return at the White House in January.

Iran claims its nuclear program is peaceful.
The resolution passed on November 21 also urged Iran to cooperate with an investigation launched after uranium particles were found at two sites that Iranian authorities had not declared as nuclear locations.
Nineteen of the 35 members of the IAEA board voted in favor of the resolution. Russia, China, and Burkina Faso opposed it, 12 members abstained, while one did not vote, diplomats who spoke on condition of anonymity told the AP.
It also calls on the IAEA to come up with a "comprehensive report" on Iran's nuclear activities by spring.
During Grossi's visit, Iran agreed with an IAEA demand to limit its stock of uranium enriched at 60 percent purity, which is still under the 90 percent threshold needed for a nuclear weapon, but it is much higher than the 3.67 percent limit it agreed to in the 2015 deal.
However, Iranian Foreign Minister Abbas Araqchi, who was Tehran's chief negotiator for the 2015 agreement, warned that Iran would not negotiate "under pressure."
Tehran has responded to previous similar resolutions by moves such as removing IAEA cameras and monitoring equipment from several nuclear sites, and increasing uranium enrichment to 60 percent purity at a second site, the Fordow plant.
