The spokesman said the Japanese decision was conveyed to a Pakistani delegation for aviation talks here which began last Monday [May 9].

Japanese delegates had told Pakistan they couldnotagree totherequestbecause Japanhas not yet restored diplomatic relations with China and because Japan Airlines has no service to mainland China.
