Myanmar's military-backed government has warned opposition leader Aung San Suu Kyi and her party to halt political activities.
State media report that the Interior Ministry has written to the Nobel Peace Prize laureate, saying her party was breaking the law by keeping its offices open and holding meetings.
Aung San Suu Kyi said she would go ahead with a planned national political tour.
She was released from house arrest in November 2010 following Myanmar's first election in 20 years.
Her National League for Democracy (NLD) was officially dissolved for refusing to re-register in order to take part in the poll, which opposition groups and Western nations condemned as a sham.
