On May 18, 2015, the Government of Mongolia, Rio Tinto and the Rio Tinto subsidiary, Turquoise Hill Resources, reached agreement on development of the underground phase of the Oyu Tolgoi mining project. The agreement, termed the “Oyu Tolgoi Underground Mine Development and Finance Plan,” sets the stage for future development and investment by Rio Tinto in Oyu Tolgoi, one of the world’s largest copper mines. In addition, the agreement is both a signal of the Government of Mongolia’s interest in attracting new investment as well as a potential catalyst for significant foreign direct investment in the resource-rich country.

In a statement released by Rio Tinto, Prime Minister Saikhanbileg Chimed of Mongolia said, “Unlocking Oyu Tolgoi’s underground mine will have a significant impact on the Mongolian economy, which will benefit Mongolian citizens for generations to come. Our joint agreement clearly positions Mongolia as an attractive country for investment and underscores the fact that Mongolia is open for business.”
