It is difficult to submit legislation for increasing regulations on purchases of Japanese broadcasters by foreign companies during the current Diet session, Taro Aso, minister of internal affairs and communications, said Friday after a Cabinet meeting.

But the government's resolve to revise the radio and broadcasting laws remains unchanged, he said.

Aso had earlier said that the government plans to submit related legislation during the current Diet session, which lasts until June 19.

The move to revise the laws is apparently intended to bar foreign firms from taking control of Japanese broadcasters in the way that Livedoor Co., a Japanese company, acquired a large stake in Nippon Broadcasting System Inc. using funds from a foreign brokerage.
