ADELAIDE, Australia, Dhu-AlQa'dah 11, 1436, Aug 26, 2015, SPA -- Japan's effort to charm Australian politicians and the public over its bid for a A$50 billion ($35.60 billion) submarine project appeared to stumble on Wednesday, with officials from Tokyo resisting pressure to commit to building the vessels in Australia, Reuters reported. Japanese defence officials and executives from Mitsubishi Heavy Industries and Kawasaki Heavy Industries made their first major pitch to build 12 stealth submarines for Australia's navy during public briefings in Adelaide, a ship-building hub. Once seen as the frontrunner to win the contract, the Japanese bid has since come under scrutiny over whether Tokyo would build any of the submarines in Australia, where manufacturing jobs are a hot-button political issue. --SPA 12:44 LOCAL TIME 09:44 GMT www.spa.gov.sa/w
