Visiting German Foreign Minister Guido Westerwelle on Friday reaffirmed Germany and Armenia would continue to deepen bilateral cooperation in such fields as the economy, politics and legislation.

The two countries had signed more than 30 treaties, Armenian Foreign Minister Edward Nalbandian noted in a joint press conference, adding they were working on new agreements and joint projects to boost their bilateral ties.

Westerwelle started a three-nation official visit in the South Caucasus region Wednesday. He visited Azerbaijan and Georgia before arriving here.

This year marks the 20th anniversary of the establishment of the two countries' diplomatic relations.
