In a message to Raisi on Saturday, Rahmon hailed the occasion as a memorable event for both nations.
He said that over the past three decades, the two countries have constantly devised plans and made efforts to elevate the level of bilateral ties and find new ways to boost comprehensive cooperation, adding that Tajikistan considers continuation of such efforts as important.
The Tajik president also underlined his country’s resolve to develop relations with Iran in various fields with a spirit of understanding, synergy and trust.
“We can enrich the ties between the two countries, which have historical and cultural commonalities, with strong resolve and sincere joint efforts … in line with the interests of our peoples,” Rahmon added.
He also wished health and success for Raisi and peace, stability, happiness and prosperity for the friendly Iranian nation.
The Islamic Republic of Iran and the Republic of Tajikistan established diplomatic relations on January 9, 1992.
The two countries have enjoyed a close and strong relationship since then.
