"Cooperation with Iran will never stop and that my company is expected to start major joint projects in the country in the near future," Chief Executive Officer (CEO) of Austria's WABAG Company Reinhard Nowotny said.
Nowotny has traveled to Tehran to take part in the 13th International Exhibition of Water Industry and Water and Wastewater Installations.
He reiterated that the removal of sanctions against Tehran has eased cooperation between the two countries.
"As to US President Donald Trump's recent statements on Iran nuclear deal, the reaction by the White House to the 2015 deal is illogical," Nowotny said.
He reiterated that the Joint Comprehensive Plan of Action (JCPOA) is an international agreement which has been accepted by Washington, and said, "The United States cannot change its stance regarding the accord."
"We will continue our engagement with Iran," the Austrian CEO said.
The 13th Water Industry Exhibition attended by 258 Iranian and 105 foreign companies ended late on Thursday.
European firms, including those from France and Germany, during the four-day exhibition, signed cooperation memoranda of understanding in a bid to expand their engagement in Iran water industry.
