Asian stocks were mixed Monday as investors monitored joint military drills between U.S. and South Korean forces and awaited a key meeting of central bankers later this week.

KEEPING SCORE: Japan's benchmark Nikkei 225 index lost 0.4 percent to 19,384.64 and South Korea's Kospi dipped 0.2 percent to 2,354.28. Hong Kong's Hang Seng rose 0.4 percent to 27,159.33 and the Shanghai Composite Index edged up 0.1 percent to 3,272.20. Australia's S&P/ASX 200 shed 0.4 percent to 5,724.20.

MOUNTAIN MEETING: Central bank officials from around the world will be gathering for an annual three-day conference at a mountain resort in Jackson Hole, Wyoming, starting Thursday. Investors will be scrutinizing remarks from the policymakers due to speak, including Fed chief Janet Yellen and European Central Bank head Mario Draghi, for any hints on the future direction of interest rates and economic stimulus programs, which will have implications for global stock markets.

MARKET VIEW: "All eyes turn to Wyoming this week, where central bank heads and academics come together to swap ideas, and this time, in all probability, to ask, 'Where on earth is the inflation we all expected, and what do we do with rates?'" said ING Economist Rob Carnell.

WAR GAMES: U.S. and South Korean forces are starting annual joint military exercises that could further rile North Korea. These war games have the potential to stoke geopolitical tensions and market jitters more than usual, given recent threats by both Trump and Pyongyang.

BYE TO BANNON: U.S. President Donald Trump's administration endured another shakeup over the weekend when divisive strategist Steve Bannon was shown the door. Now that Bannon, who had called in an interview for an "economic war" with China, is gone, investors may feel it's a bit more likely the administration can achieve at least some of its pro-business agenda.
