The couple have enlisted the help of one of the country's leading monks to plan a trip to an orphanage, DAILY MAIL UK reports.

According to an insider, Angelina, 32, is desperate to offer help to troubled nations, and feels the repressive Republic of Myanmar, or Burma, is the ideal place to adopt another child – preferably, a girl.

The source said: "Angelina feels she is barely making a dent in the suffering she sees throughout the Third World as she travels incognito to different countries as a United Nations representative.

"She wants to step up her action in what she calls Red Alert areas, the most seriously troubled, war-torn areas in the world.

"She's in talks to go into Burma and help with students and AIDS victims who are suffering terribly."

The source added Angelina had been talking to a monk about a safe travel route through the military state and a visit to an orphanage.

She is said to believe adopting another girl would balance her family and a child from Burma would fit into its racial mix.
