Commemorative Stationery of Russia-Myanmar Diplomatic Relation

In my earlier post, I documented the postal stationery envelope released to mark the 70th anniversary of diplomatic relations between Russia and Myanmar. This isn't the inaugural instance of Russia releasing philatelic materials for such occasions; previously, commemorative envelopes adorned with illustrated cachets were issued for the 25th, 30th, and 40th anniversaries as well.

In this post, I aim to compile a comprehensive record of all four covers, encompassing the postal stationery envelopes issued to commemorate the 25th, 30th, 40th, and 70th anniversaries of Russia-Myanmar Diplomatic Relations.

25th Anniversary (1973)

30th Anniversary (1978)

40th Anniversary (1988)

70th Anniversary (2018)

First three were issued under Soviet Union and the last one was issued under Russia.  The USSR established diplomatic relations with Myanmar upon the latter's independence in 1948, which remain to the present day through Russia.  Myanmar also issued the stamp to commemorate 65th anniversary of diplomatic relations with Russia in 2013.
