WASHINGTON, Jan. 22 (Xinhua) -- The United States will send diplomats to Europe to discuss the Iran nuclear deal with their European counterparts, Secretary of State Rex Tillerson said on Monday.

"We have a team traveling, actually. They're coming to Europe. A team that will meet with counterparts," Tillerson told reporters en route to France, according to a statement released by the U.S. State Department.

Tillerson's words came over a week after U.S. President Donald Trump threatened a withdrawal from the Iran nuclear deal if the U.S. Congress and his European allies cannot fix the alleged "disastrous flaws."

European top diplomats reasserted their commitments to Iran nuclear deal ahead of Trump's decision.

Tillerson said that the U.S. diplomatic team will discuss U.S. concerns about the accord with the European officials "in a package."

Trump has constantly criticized the Iran nuclear deal inked between the six world powers, namely China, Russia, Britain, France, the United States and Germany, and Iran in 2015, in which the West promised to relieve sanctions on Tehran in exchange for a halt in Iran's efforts to develop a nuclear weapon.

Apart from engaging with its European partners, the Trump administration is also working with Congress on a legislation, which seeks provisions to permanently prevent Iran from acquiring nuclear weapons and subject Iran's long-range missile program to severe sanctions.

Tillerson is on a seven-day trip to Europe kicking off on Sunday, covering London, Paris, Warsaw and Davos. His tour came as the trans-Atlantic ties have been challenged by widening division over the U.S. proposed revision of the Iran nuclear deal, among others.
