A top posts and telecommunications regulator on Monday brushed aside a call by the head of Nippon Telegraph and Telephone Corp. to revise the law governing NTT's operations to resolve a row between Japan and the United States.

"Time is short to discuss NTT's operations" before upcoming bilateral negotiations, Vice Minister of Posts and Telecommunications Masahito Tani told a regular press conference.

NTT President Junichiro Miyazu said last week that bilateral talks "should be promoted by including the issue of revising the NTT law."
