TEHRAN, Oct. 5 (Xinhua) -- Iran's Supreme Leader Ayatollah Ali Khamenei endorsed on Saturday the diplomatic efforts of President Hassan Rouhani at the recent UN General Assembly, but criticized some aspects of his UN visit.
On the positive side, Khamenei's remarks were an allusion to the diplomatic efforts of the Iranian delegation to the United Nations, which aimed to criticize Western pressures on Iran over the country's controversial nuclear program and to gain support for what the Iranians called "rights to civilian nuclear program."
On the sidelines of the UN sessions, the Iranian diplomatic delegation held meetings with some Western officials and explained to them Iran's foreign policy to " constructively interact" with the world.
Besides, Rouhani held a 15-minute telephone conversation with his U.S. counterpart Barack Obama, the first talk of the two countries' heads of state since the outbreak of Tehran hostage crisis more than three decades ago. During the conversation, Obama called for solving Iran's nuclear issue in a diplomatic way.
"We support the diplomatic initiative of the (Iranian) government, including its (diplomacy) in New York visit, since we have trust in the government and are optimistic" about its policies, Khamenei was quoted as saying by ISNA news agency.
"We have trust in our own officials and expect them to be cognizant about diverse aspect (of diplomacy), take resolute steps and not to forget the national interests," the Iranian leader said in his first public comments on the foreign policy of the country' s new administration.
In the meantime, Khamenei's Saturday remarks were an echo of his dissatisfaction with the outcome of the UN diplomacy which also aimed at creating proximity with the United States and appeasing tensions between the two countries.
"However, some aspects of the New York visit (by the Iranian diplomatic delegation) were inappropriate, " Khamenei told a military gathering on Saturday, adding that "we consider the U.S. government as unreliable, arrogant, illogical and the one who breaks its promises."
The United States is "untrustworthy" and it serves the interests of the Zionist regime of Israel, he said in a reference to some contacts between Iranian and the U.S. officials on the sidelines of the recent UN meeting to normalize relations.
Khamenei did not elaborate further on the "inappropriate" aspect of the president's visit in New York, but emphasized that " we are pessimistic toward the (restoration of relations) with the Americans" who have intimate relations with Israel.
Only a few days after the telephone conversation with Rouhani, Obama reassured the Israeli Prime Minister Benjamin Netanyahu that he will take no options off the table, including military options, in terms of making sure there's no nuclear weapons in Iran.
On Saturday, Obama said Iran is still "a year or more" away from building a nuclear weapon, citing U.S. intelligence assessments.
He admitted that these assessments are "more conservative" than the Israelis, who claim Iran is just months away from acquiring nuclear capability.
Obama added that the world must test whether the Iranian president is sincere about seeking a diplomatic solution to the nuclear standoff.
The remarks by the U.S. president have displeased the Iranian leaders who expected soft rhetoric from him after the positive gestures from the Iranians in the UN General Assembly.
Rouhani's moderate foreign policies have also drawn criticism from Iranian hardliners, which underlines difficulties for the Islamic republic and the United States to ease decades of hostility.
On Sept. 30, the commander of Iran's powerful Islamic Revolution Guards Corps (IRGC), Major General Mohammad-Ali Jafari, criticized the phone conversation between Rouhani and Obama, saying that the recent telephone conversation of Iranian president with his U.S. counterpart Obama in New York before "practical" signs by the United States over bilateral relations was a "mistake. "
"Total lift of sanctions" by the United States against the Islamic republic and "endorsement of Iran's nuclear rights" are among the pre-requisites for normalization of their ties, said Jafari.
Meanwhile, while addressing the UN General Assembly on Tuesday, Netanyahu urged the international community to tighten the sanctions on Tehran over its controversial nuclear program.
Also, during a meeting with Obama at the White House on Sept. 30, Netanyahu expressed deep mistrust toward Rouhani's conciliatory overture. He vowed to deal with Iran's nuclear activities and to dismantle its nuclear sites even if it stands alone.
"Those who are used to threatening Iran should know that our response to any threat against the Iranians would be serious and hard," Khamenei said on Saturday.
