(CNN) Iran agreed to a four-point plan for talks with the United States during the UN General Assembly last week, until US President Donald Trump threatened to increase sanctions against Tehran, President Hassan Rouhani said in a televised speech on Wednesday.

French President Emmanuel Macron made the proposals and tried to broker a meeting between Trump and Rouhani, the Iranian leader said. "(The) French president for the second time in 24 hours met with me and he presented that plan to me, and I said that the generality of that plan from our point of view (is) acceptable," Rouhani said.

Rouhani said the four-point program stipulated that Iran should not seek nuclear weapons, should abide by regional peace, help to contribute to peace, and, in exchange, the US would lift all sanctions against Tehran and allow Iranian exports "immediately."

Tehran balked when Trump doubled down on increasing sanctions in two announcements he made over 24 hours, the Iranian president said.

In his UN speech last week, Trump warned he would tighten economic penalties if Iran continued its "bloodlust." CNN has reached out to the US administration for comment.
