Brazil, the Third World's biggest debtor, has brought interest payments on its commercial bank debt up to date for the first time since early last year, the Central Bank said on Saturday.

A Central Bank spokesman said Brazil had paid $3.76 billion to Citibank in New York. Brazil decreed a moratorium on interest payments on its $70 billion bank debt on Feb. 20, 1987, but effectively ended the action about 10 months later.
