Burma is accusing the United States and Britain of interfering in its internal affairs by offering training courses to members of the opposition National League for Democracy party.
The state-run New Light of Myanmar reports Tuesday that party members can take English proficiency and international relations courses at the embassies free of charge, unlike other students.
The newspaper calls the courses "illegal" and condemns the interference in state affairs.
The director of the American Center in Rangoon, Thomas Pierce, says the center has been offering English and other courses to hundreds of Burmese citizens for 50 years.
He says Burmese officials would not say what laws they have broken.
The National League for Democracy won parliamentary elections in 1990 but was never allowed to take power.
More than 100 senior party officials are in prison and leader Aung San Suu Kyi is under house arrest.
Burmese media have recently reported mass resignations from the party by officials who supposedly left because they said the opposition group is linked to terrorists.
The reports revived fears that Burma's military government is considering banning the party.
