Araghchi, speaking days after leading an economic delegation to France, ruled out any renegotiation of the JCPOA, but said Iran was open to talks on how to implement it better in return for us dollars.
Tensions between the USA and Iran have increased in recent months, due to President Trump increasing sanctions on Tehran.
"Our American partners are openly seeking to provoke Iran with the support of some of their regional allies", he said.
"If we had 20 issues of disagreement with the Europeans in the past, today there are three issues", he said.
"Although the European Union and particularly France have goodwill, they should convince the USA to cooperate with them", a senior Iranian official familiar with the negotiations told Reuters.
President Trump abandoned the accord previous year and reimposed sanctions in the fall, violating the terms of the agreement.
Crimea has offered Iran access to its ports as a way for Tehran to avoid Western sanctions on oil exports, a senior official in the annexed region's Kremlin-backed administration told Russian media.
But Iran has been slowly breaching the deal's requirements as a way to pressure other states to help relieve some of the economic stress caused by Washington's decision to reimpose harsh sanctions on several of its key industries.
The network sold more than $500 million worth of oil this spring, mostly to Syria, benefitting both President Bashar al-Assad and militant Lebanese allies Hezbollah, the Treasury Department said.
The diplomat, who spoke on condition of anonymity, said such a move would "make the (mediation) work more complicated", but said France would remain engaged with Tehran to try promote dialogue.
He warned that the USA excessive use of sanctions is turning to an ever-increasing threat to the country's own economy.
Deputy Foreign Minister Abbas Araghchi's remarks come after days of intense efforts by Tehran to convince European nations to help Iran sell its oil overseas.
Iran has always given "negative" response to the talk offers with the US, Xinhua news agency quoted Rouhani as saying.
Speaking during a teleconference with reporters, he emphasized that the US policy remained to exert "maximum pressure on Iran" to force it to the negotiating table over its nuclear and missiles programs.
A week later, it announced it had exceeded a 3.67% cap on the purity of its uranium stocks.
The UN agency also said Iran continues to enrich uranium up to 4.5 percent, above the 3.67 percent allowed under the JCPOA but still far below weapons-grade levels of 90 percent.
