Former Untac commander Lt. Gen. John Sanderson arrived in Cambodia Thursday to work as a volunteer on land mine issues for an Australian aid agency.

Sanderson was the commander of the military component of the UN transition force in the early 1990s.

Sanderson will observe and update the operations of Austcare's Integrated Mine Action and Community Development Program and "witness personally Cambodia's continued path to development made possible as a result of the peace process in which he played such an important part," according to a statement.
