IRNA � The Office of the President of the Islamic Republic of Iran in a statement on Monday reacted to calls by 'some parties' inside the country urging President Hassan Rouhani to apologize for signing the Iran nuclear deal.

Iran's Assembly of Experts urged President Hassan Rouhani in a statement on Sunday to apologize to the people of Iran for signing the Iran nuclear deal, also known as the Joint Comprehensive Plan of Action (JCPOA).

'Unfortunately, those who should be regretful about their previous faulty stances, tend instead to relentlessly attack national achievements,' the statement said, referring to remarks and statements made by 'some parties', including 'respected dignitaries' in the aftermath of US unilateral withdrawal of the JCPOA on May 8.

'The Government of the Islamic Republic of Iran, as a government elected by the people, has from the outset committed itself to realizing the public demand through constructive engagement with the world,' the statement said.

The Presidential Office in its statement urged that the government has never stopped 'freeing the country from brutal sanctions' and 'blocking dangerous resolutions of the United Nations Security Council'.

In order to safeguard the interests of the Iranian people, the Government has always upheld 'three principles of dignity, wisdom and prudence,' it said.

The statement further noted that Iran's nuclear negotiating team has done all in its capacity to secure the country 'the most benefits available and to give the least concessions.'

'The main strategy adopted by the Government during intensive and long negotiations with the six world powers and the European Union, has revolved around national interests of the country,' it said.

The statement by the office of the Iranian President insisted that during the nuclear talks with the P5+1 group of nations, the Iranian negotiators have not compromised over the country's rights, and strategic capabilities nor have been any bargaining regarding the issue.

The JCPOA from a global perspective is a unique achievement of diplomacy, peace and regional and international security that brought to an end an international consensus shaped against Iran, removed international sanctions and legitimized Iran's peaceful nuclear program.

Referring to the decision by the US President Donald Trump to pull out from the 2015 landmark international nuclear accord, the statement reiterated that preserving national unity while Iran is at a critical juncture, is a must.

Signing the nuclear deal enhanced Iran's defensive power and reinforced its regional stance, the statement said.

It is inappropriate to attack the government and try to undermine the achievements made by the country, it cautioned.
