Officials from the health ministry of Burma has summoned aid workers from international non-governmental organizations (INGOs) to Naypyidaw, new capital of the country, last week and warned to follow strictly the rules and to report detail of their field trips to the government.

The new rules also required foreigners working for INGOs to accompany with a liasion officer from the ministry when travelling around the country.

Government also further limited the rules on collecting data and surveying in the country, it was said in the minutes of the meeting seen by the BBC.

The new rules prohibit collecting information other than those related to public health.

More than thirty INGOs are currently operating in Burma implementing health related projects.
