FACTBOX: Key facts about Myanmar

(Reuters) - Nearly 4,000 people were killed and thousands were missing in two of Myanmar's devastated cyclone regions, state television reported on Monday.

Myanmar's military, which has ruled for 46 years and is shunned by the West, has not issued an appeal for help since Saturday's storm with wind speeds of 190 kph (120 mph).

Here are some key facts about Myanmar, a former British colony:

-- Having won independence in 1948, what was then called Burma was roiled by political feuding and ethnic guerrilla conflicts until a 1962 coup. It has been run by the army ever since and ethnic insurgencies, in many cases fuelled by the opium trade, continue to rumble on.

-- Although it is home to more than 100 different ethnic groups, nearly 70 percent of its 53 million people are ethnic Burman. Significant minorities are the Shan and predominantly Christian Karen.

-- Ranked as one of Asia's most promising economies in the 1950s, it is now one of the region's poorest nations, due mainly to decades of disastrous socialist central planning by the military government.

It possesses some of Asia's largest reserves of natural gas, as well as the world's finest rubies and extensive teak forests.

-- Opposition leader Aung San Suu Kyi, the daughter of independence hero Aung San, has been in prison or under house arrest for more than 12 of the last 18 years.

Her National League for Democracy party won more than 80 percent of the vote in a 1990 election which the military then ignored. She was awarded the Nobel Peace Prize the following year, while still under house arrest.
