The expo was kicked off on Thursday and will run until March 8 in the Tajik capital, a Press TV correspondent in Dushanbe reported.
Over 25 firms from Iran, Tajikistan, and Afghanistan have participated in the event, displaying their products necessary for Nowruz holidays.
Some 18 Iranian firms have put on show various products, including home appliances, textiles, foodstuff, handicrafts, and hand-woven Persian carpets.
An official of Tajikistan Chamber of Commerce told Press TV that such exhibitions would pave the way for strengthening trade and economic ties between the two countries.
The total trade transaction of the two countries hit $400 million in 2010, indicating a 35-percent increase comparing to the figure of the previous year.
Nowruz, which coincides with the first day of spring on the solar calendar, is mostly celebrated in Iran, Kyrgyzstan, Azerbaijan, India, Afghanistan, Tajikistan, Pakistan, Turkey, and Uzbekistan.
Nowruz was registered on UNESCO’s List of the Intangible Cultural Heritage of Humanity in September 2009.
Iran and Tajikistan enjoy robust trade relations. The exhibit will help boost trade with Iranian firms while allowing Tajik companies to acquire the expertise they need to develop their own businesses.
Iranian companies are also currently involved in several development projects in the country, including the construction of a dam, a hydroelectric power plant, and a tunnel.
Earlier in November 2010, Iran also held its ninth exclusive expo in Dushanbe with around 75 Iranian firms in attendance.
