<h1>Asian markets mostly higher as investors weigh U.S.-Russia summit outcomes, Jackson Hole, Ukraine meeting and mixed U.S. data</h1> Asian markets were mostly higher as investors reacted to a lack of breakthroughs from a summit between the U.S. and Russian leaders and awaited a Washington meeting with the Ukrainian leader and a central bank gathering in Jackson Hole. Mixed U.S. economic reports tempered expectations for a September Federal Reserve rate cut ahead of the Fed chair's speech. Major indexes showed modest moves across the region, with some national indices up and others down. Market action was also driven by corporate news: a large investor's purchase lifted a major insurer's stock sharply, while semiconductor and data-storage firms fell on weaker near-term guidance.
