Taiwan's Foreign Ministry said Sunday it is working to sign an agreement with Japan governing scientific research in disputed waters of the East China Sea.

In a statement, the ministry said Taiwan and Japan agreed last year to establish a working group to discuss scientific research in overlapping exclusive economic zones.

Taiwan's Foreign Ministry was responding to a report published Sunday by the Sankei Shimbun, a right-wing Japanese daily, quoting the Japan Coast Guard as saying that last year, Taiwan conducted the most unauthorized maritime research activities in Japan's EEZ in a decade.
