Taiwan's Coast Guard Administration (CGA) said Wednesday it will take punitive action against anyone who makes false accusations of any kind against the Japanese coastguard, in the most recent controversy near the disputed Tiaoyutai Islands. CGA Vice Minister Wang Chung-yi said at a press conference that CGA inspectors have found no evidence that a Keelung-registered fishing boat Chuan Chia Fu had been rammed by Japanese coastguard vessels in waters near the Tiaoyutai Islands Tuesday. CGA inspectors boarded the fishing boat to inspect it immediately after its arrival at Keelung's Shenao harbor early Wednesday morning, after it was reported that the boat had been rammed by Japanese vessels near the Tiaoyutais, Wang said. According to Wang, the Chuan Chia Fu departed from Shenao Monday on a recreational fishing trip, carrying eight people -- its skipper, two foreign workers, three anglers and two activists who support Taiwan's claim to the Tiaoyutai Islands. One of the activists said Tuesday that the fishing boat was rammed three times by Japanese coastguard vessels after it entered the area near the uninhabited Tiaoyutai Islands, which are claimed by Taiwan, Japan and China. The activist, identified as Huang Hsih-lin, also accused the CGA of ignoring the boat's call for help when the incident occurred. However, Wang said the records show that when the CGA received phone calls from the fishing boat, it was 30 nautical miles off the Tiaoyutais, and 79 nautical miles outside Shenao harbor. At that time, there were three Japanese ships and two CGA vessels in the area, according to the records, which clearly show that the two Japanese coastguard vessels were about 10 nautical miles away from Chuan Chia Fu, as was the CGA vessel Mou Hsing, Wang said. He further said that Huang had called the CGA 118 hotline on a satellite phone but the connection failed. Huang then called a CGA official's cell phone and said the fishing boat was 'on its way to Shenao,' according to Wang. There was no mention of the boat being in any danger, he added. The CGA has launched an investigation into the allegations and anyone found making false statements will be brought to justice, he stressed. Meanwhile, the Taipei office of the Japan Interchange Association, which is in charge of Taiwan-Japan exchanges in the absence of diplomatic ties, said that the Japan coastguard vessels had maintained a safe distance from the Taiwanese boat. Not once did the coastguard attempt to run down the fishing boat or board it, the office said in a statement released earlier in the day. The reports in the Taiwan media that the Japanese coastguard had rammed the Chuan Chia Fu three times and had attempted twice to board it are inaccurate, the office said. The only action the Japanese coastguard vessels took was to order the Chuan Chia Fu to leave, as they said the boat was fishing illegally in Japan's territorial waters, the office said. The coastguard vessels kept a safe distance of at least 50 meters away from the Chuan Chia Fu at all times and there was no question of onboard inspections, according to the office.
