Foreign Minister Katsuya Okada cast a positive light Thursday on the pace of reform in the Democratic Party of Japan's first three weeks in power and said he expected the party to continue implementing change right up to the next general election.

Speaking at the Foreign Correspondents' Club of Japan, Okada outlined the steps he has taken since assuming office, including commissioning an investigation into the so-called secret pacts with the United States that allow U.S. ships and aircraft carrying nuclear arms to enter Japan.

The results of the investigation are to be reported by the end of November.
