Mongolian Ministry of Foreign Affairs and Trade held a seminar Thursday to commemorate the 25th anniversary of diplomatic relations between Mongolia and the United States.

Addressing an audience of some 100 government officials, scholars and U.S. diplomats, U.S. ambassador to Mongolia Jonathan Addleton said the two countries have expanded cooperation in a wide range of areas over the past years and more and more big U.S. companies have been engaged in Mongolia's economic development.

The ambassador also mentioned Mongolia's "active role in international peacekeeping missions."

Mongolia-U.S. relations have developed rapidly over the past years as the two countries have agreed to build a "comprehensive partnership based on common strategic interests."
