The White House says President Bush called UN Secretary-General Ban Ki-moon ahead of the return of a UN envoy to Burma.

Press secretary Dana Perino said President Bush today – Tuesday emphasized the need to maintain a clear message to Burma’s military government.

Mr. Bush said the message should be that real political change aimed at the restoration of human rights and democracy is required to end the crisis.

The White House says Ban and Mr. Bush agreed on the importance of serious dialogue between the military government and the opposition – particularly pro-democracy leader Aung San Suu Kyi.

Ban said UN special envoy Ibrahim Gambari will return to Burma on Thursday.

Gambari has said he hopes to meet again with Aung San Suu Kyi and Burma’s top military leader, General Than Shwe.
