After returning to Moscow for the first time in 18 years, NewsHour senior correspondent Margaret Warner has been observing the "overwhelming" changes in the city from a key vantage point at the Kremlin.

Warner spent a decade as a diplomatic correspondent for Newsweek magazine and traveled to Moscow many times as then-U.S. Secretary of State James Baker negotiated the collapse of communism with Soviet leaders.

She notes the dramatic change in the city's skyline and the shops filled with goods, but also finds one familiar spot -- a popular ice cream kiosk.

Warner is reporting on political, economic and social issues in Russia ahead of President Barack Obama's visit to Moscow in early July. Watch for her broadcast reports beginning the week of June 29.
