The United States says Burma's military intelligence service spies on American diplomats, frustrating their work to improve human rights in the country.
The allegations are contained in the latest U.S. State Department report (released in October) on U.S. activities aimed at supporting democracy activists in Burma.
The report says Burma's ruling military taps telephones, films meetings, monitors mail and pressures citizens working for diplomats to report on their employer's activities.
The report says the movements and conversations of U.S. and other foerign diplomats in Burma are assumed to be heavily monitored at all times by Burma's military intelligence.
The document adds that non-governmental organizations also face serious obstacles.
The State Department says it continues to lobby other governments to impose their own sanctions on Burma's military rulers in an effort to secure the release of opposition leader Aung San Suu Kyi and restore democracy in the country.
