The Chinese and Iranian foreign ministers on Saturday signed a 25-year cooperation agreement in a ceremony carried lived on state television. “Our relations with Iran will not be affected by the current situation, but will be permanent and strategic,” Chinese Foreign Minister Wang Yi was earlier quoted by Iranian news agencies as saying. “Iran decides independently on its relations with other countries and is not like some countries that change their position with one phone call.” “The signing of the comprehensive cooperation program of Iran and the People’s Republic of China by the foreign ministers of the two countries is another program of this two-day trip,” state news agency IRNA said on Friday. “This document is a complete roadmap with strategic political and economic clauses covering trade, economic and transportation cooperation ... with a special focus on the private sectors of the two sides,” Foreign Ministry spokesman Saeed Khatibzadeh told state TV. In 2016, China, Iran’s largest trading partner, agreed to boost bilateral trade by more than 10 times to $600 billion in the next decade.
