It's time for you to take 10 minutes away from your schoolwork and let CNN Student News catch you up on the world's headlines. I'm your guide, Carl Azuz. We're starting today in the Pacific. More U.S. troops could be headed to Australia. That's one of the headlines that's expected to come out of President Obama's trip there this week. The U.S. and Australia are allies. Australia has supported the U.S. in the wars in Iraq and Afghanistan, as well as other military conflicts in the 20th century. Now some countries are concerned about how strong China is becoming in the Western Pacific region. So as Brianna Keilar explains, having more American troops in Australia could be seen as a kind of defense against the spread of China's influence. The third time's a charm. After canceling planned trips to Australia twice now, President Obama is finally headed down under. While the president's visit to the APEC summit here in Hawaii was more about emphasizing U.S. trade interests in Asia, his visit to Australia is more about U.S. military interests in the region.
