WASHINGTON, June 24 (Xinhua) -- U.S. President Donald Trump said Wednesday that Iran had assured Washington it is not seeking tolls, insurance fees, or other charges from ships transiting the Strait of Hormuz, warning that negotiations between the two sides would end immediately if the information proved false.

"Iran has informed the U.S. that, despite troublemaking Fake News reporting to the contrary, there are 'NO TOLLS, NO INSURANCE COSTS, & NO OTHER CHARGES OF ANY KIND BEING SOUGHT OR RECEIVED BY IRAN ON SHIPS TRAVELING THE STRAIT OF HORMUZ,'" Trump wrote on his Truth Social.

"If this is false information, negotiations would end, immediately!" Trump warned.

Trump also dismissed speculation that Washington had released money directly to Tehran.

"Additionally, no money has been given to Iran, or released from their money to them, by the U.S.," Trump wrote.

However, the president said the White House could release a portion of Iranian assets under U.S. control for the purchase of agricultural products, including corn, wheat and soybeans, only from American farmers.

"We will be releasing some of their money, that is totally controlled by us, to our Farmers and Ranchers, for the purchase of Corn, Wheat, Soybeans, and more," Trump said, adding "we will be purchasing it for them exclusively from the United States."

Trump's remarks came one day after Iran and Oman issued a joint statement affirming their commitment to ensuring safe passage through the Strait of Hormuz and agreeing to continue their discussions to reach an understanding on the future management of navigation in the strait and the related charging service "costs."

Iran's semi-official Fars news agency reported Tuesday that only a limited number of vessels are allowed to pass through the strait each day based on coordination with the Navy of Iran's Islamic Revolution Guard Corps.

According to Fars, the strait had been closed for days following Israel's "hostile" actions against Lebanon and the U.S. "violations" of its commitments under the recently signed U.S.-Iran memorandum of understanding (MoU), which led to a 60-day roadmap toward a final peace agreement.
