Eight major countries including Japan expressed concern over the treatment of prodemocracy leader Aung San Suu Kyi by Myanmar's military government, Foreign Ministry spokesman Sadaaki Numata said Tuesday.

The other countries are: Australia, Britain, France, Germany, Italy, South Korea and the United States. The eight countries' ambassadors to Myanmar also called for dialogue between the two parties.

The ambassadors planned to jointly convey the message to the military government but were unable to arrange appointments, Numata said. Confrontations between Suu Kyi and the military government have been escalating ever since the government began restricting her travel.

The situation in Myanmar has been tense since late June, when Suu Kyi's National League for Democracy set a deadline of Aug. 21 to convene the 1990 Parliament. The NLD overwhelmingly won the 1990 general election, but the ruling generals have not allowed the Parliament to convene.
