Compare the techniques seen in the works of Russian impressionist painters with those of the French impressionists?

Although Russian impressionism became a popular artistic
style in the Soviet Union nearly a hundred years after the French impressionists made
their mark, stylistically, the Russian artists embraced the same techniques:  heavy
brush strokes, bold, vibrant colors, and an emphasis on spontaneous, and often plein-air
(out in the open) subject matter.  Despite these similarities, Russian artists put a
unique stamp on their work, which was informed by Soviet isolationism and lack of
exposure to the West until the "perestroika" in the early 90's.  Another parallel exists
when one looks at the political and social conditions of the artists' respective
countries at the time they were doing the great part of their work.  Both France in the
late 1800's, and Russia in the mid to late 1900's, were in the midst of social/political
upheaval and change, characteristics that are reflected in the work of both French and
Russian impressionists.
