(VOVworld) - Japan has asked China to refrain and not fueling escalating tension in the East Sea. Japan’s Chief Cabinet Secretary Yoshihide Suga told reporters in Tokyo on Tuesday that the sinking of the Vietnamese boat reflects “very dangerous actions which threaten human life,”. He said that “it is important that all nations work for the return to regional stability, act calmly, carefully in accordance with international law, and don’t act unilaterally to increase tensions.” Japanese Defense Minister Itsunori Onodera said the sinking was a serious issue and calling for proper disclosure of the incident to the world community. US Bloomberg, Australian ABC and UK Guardian criticized the Chinese ram sinking the Vietnamese boat, especially in the backdrop of tension following China’s illegal placement of an oil rig in Vietnam’s waters.
