Due to its The Australia, New Zealand, United States Security Treaty (ANZUS) treaty obligations, Australia could possibly be drawn into military action if any further attack bursts in Korea, Foreign Minister Kevin Rudd said on Sunday, urging restraint in the volatile region. Tensions between the Democratic People's Republic of Korea and South Korea have heightened in the past week after the artillery skirmish between the DPRK and South Korea off the west coast. The DPRK has warned that naval exercises by the U.S. and South Korea in the region on Sunday could have dire consequences. Australia has alliance obligations through the ANZUS treaty of 1951 with the United States. According to Rudd, the ANZUS treaty was clear that if there were attacks on the allies' armed forces in the Pacific area, Australia would have to act to meet the common danger.
