Japanese Foreign Minister Yoshimasa Hayashi told reporters that Japan would take "necessary action (on China's aquatic product ban) under various routes including the WTO framework". Filing a WTO complaint might become an option if protesting to China through diplomatic routes is ineffective, Economic Security Minister Sanae Takaichi said separately. Japan's National Police Agency has received 225 reports of harassment calls to date, Jiji News reported, and the government said it was seeking help from telecommunications companies to block the calls. NTT and other phone companies including KDDI (9433.T) and SoftBank Corp (9434.T) are discussing measures following the government's request. "It is extremely regrettable and concerning about the large number of harassment calls that have likely come from China," Trade Minister Yasutoshi Nishimura said during a news conference.
