TEHRAN – Iran has rejected as “unjustified and invalid” concerns voiced by the Joe Biden administration over Tehran’s expansion of trade cooperation with other states, saying the latest agreements with Russia and Pakistan are in line with Iran’s emphasis on the policy of good neighborliness. Foreign Ministry spokesman Nasser Kanaani said the signing of an agreement on the completion of the Rasht-Astara railroad and inauguration of joint border projects with Pakistan are all part of Iran’s “neighbor-oriented” policy.
