Although international support for physical education and sport in developing countries has in recent years beenpromoted by UNESCO, other international cooperation agencies and NGOs, the curriculum time allotted for physi-cal education within schools is being reduced due to the low educational priority it commands and a lack of ade-quate facilities.This paper examines the nature of international cooperation in the field of physical education through a casestudy of government policies and school education in Lao, and reveals the existence of three curricula aspects, con-sisting of Intended Curriculum, Implemented Curriculum, and Attained Curriculum.In terms of improving physical education in a particular country through international cooperation, two factorsare paramount.The first is to develop the curriculum itself by means of improved textbook content, teacher guide-books and other teaching materials.The second factor is to develop appropriate systems through which gapsbetween the Intended Curriculum, Implemented Curriculum, and Attained Curriculum can be reduced by, for exam-ple, generating a system of in-service training, a distribution network for textbooks and a good communication sys-tem between government and schools.
