The 19 Fellows of the Center for International Affairs (CfIA) this year will include several experts on African and Asian affairs, and will be "particularly strong on the economic development of poor countries," Benjamin H. Brown, advisor to the Fellows, said yesterday.

Each of the Fellows will conduct research, take classes and attend seminars at the CfIA, Brown said. The fellowship does not include a monetary stipend, so most of the Fellows will be supported by their native governments, or by American corporations, he added.

Vietnam, will conduct research on the foreign policy of China from the death of Mao Tse-Tung to today, and will attempt an analysis of American energy policy.

The Fellows include Sang Moon Chang, a South Korean diplomat and Chief of Protocol, Raymond M. Dafter, a British journalist, Peter Lynn Sinai, an Indian diplomat, and Kifle Wodajo, who resigned in 1977 as Foreign Minister in the Provisional Military Government of Ethiopia.

Marc Menguy, French diplomat and Counselor of the Hanoi Embassy in 1973-76, said yesterday he is planning to study U.S.-China foreign policy and the current balance of power in China.

When asked how he will spend his time in Cambridge he said, "I will sit and read," but added that he is willing to meet undergraduates because "it is important to know what young people feel about world affairs."

Carlos M. Villar, chief of operations in Brazil for the Interamerican Development Bank (IADB), plans to attend, seminars, audit economics and political science courses and write a paper.
