Bali , Indonesia ( CNN ) -- President Barack Obama took part Friday in the ASEAN ( Association of Southeast Asian Nations ) economic summit and hailed an airplane sales deal between Boeing and an Indonesian airline . Obama was in Bali , Indonesia , for the ASEAN meeting in a region that accounts for more than half of the world 's GDP . He held bilateral talks with India , the Philippines and Malaysia beforehand . Obama helped announce a large plane order for U.S.-based Boeing to Lion Air . `` For the last several days , I 've been talking about how we have to make sure that we 've got a presence in this region , that it can result directly in jobs at home , '' Obama said in a statement . `` And what we see here -- a multibillion-dollar deal between Lion Air -- one of the fastest-growing airlines not just in the region , but in the world -- and Boeing is going to result in over 100,000 jobs back in the United States of America , over a long period of time . '' He said more than 200 planes were in the order . ASEAN leaders , meanwhile , agreed that Myanmar can chair the regional bloc in 2014 , amid some signs of reform . Some critics say it is still too early to award the high-profile role to Myanmar , where between 600 and 1,000 political prisoners are believed to remain behind bars . The Asian leg of Obama 's trip follows two days spent in Australia , where he declared that the United States will increase its military presence and expand its role in shaping the Asia Pacific region . `` Our enduring interests in the region demand our enduring presence in this region , '' Obama told the Australian Parliament . `` The United States is a Pacific power , and we are here to stay . '' He announced an agreement with Australia on Wednesday that will expand military cooperation between the longtime allies and boost America 's presence in the region . In a speech a day later , Obama made it clear that the military expansion is a top priority in the wake of the Iraq and Afghanistan wars , even as the United States faces the need to reduce mounting federal deficits and debt . `` As we end today 's wars , I have directed my national security team to make our presence and missions in the Asia Pacific a top priority , '' Obama said . `` As a result , reductions in U.S. defense spending will not -- I repeat , will not -- come at the expense of the Asia Pacific . '' The speech on the second day of his two-day trip to Australia , Obama 's first as president , signaled a policy objective to compete head-on with China for influence in the region while also providing security assurances for allies . Deputy National Security Adviser Ben Rhodes told reporters that the policy comes in part from nations of the region seeking increased U.S. presence . `` The ability of the United States to help respond to contingencies is something that has been welcomed in recent years , whether , again , it was work that we 're doing in the Philippines to counter violent extremism , work that we 're doing to counter piracy in the region , the response to the tsunami in Indonesia , '' Rhodes said . `` So in other words , there 's a demand signal from the nations of the region , and this is something that we 're doing in concert with one of our closest allies . So we believe it 's not just entirely appropriate , but an important step to dealing with the challenges of the future of the Asia Pacific region . '' Under the military agreement announced Wednesday , up to 250 U.S. Marines will be sent to Darwin and the northern region of Australia for military exercises and training . Over the next several years their numbers are expected to climb to 2,500 -- a full Marine ground task force . Before departing Australia for Indonesia , the president , along with some U.S. Marines , visited a military base in Darwin . While speaking to the troops there , Obama thanked them for their service and praised the two nations ' alliance , which is now 60 years old , and said he looks forward to a deepening of the alliance . Going forward , our purpose is the same as it was 60 years ago -- `` the preservation of peace and security . And in a larger sense , you 're answering the question once posed by the great Banjo Paterson . Of Australia , he wrote , 'Hath she the strength for the burden laid upon her , hath she the power to protect and guard her own ? ' '' The president 's Australian visit -- postponed twice in 2009 and 2010 due to the massive oil spill in the Gulf of Mexico and other domestic political considerations -- highlights a changing balance of power in the Pacific as China expands its military reach and the United States works to reduce its military footprint in Japan .
