    Tourists visit the Ruins of St. Paul's in Macao, south China, May 2, 2026. (Xinhua/Cheong Kam Ka)Nearly three decades after its return to China, Macao continues to explore new ways to sustain stability and prosperity under the "one country, two systems" policy, with successive five-year plans offering a long-term roadmap for its development.
Macao and its neighbor Hong Kong are China's two special administrative regions (SARs) governed under the "one country, two systems" policy. This arrangement, in place since China resumed the exercise of sovereignty over the two cities in the late 1990s, allows them to maintain their capitalist systems and ways of life within socialist China.
The third five-year plan of the Macao SAR, unveiled on Tuesday, sets out policy priorities for the next stage, focusing on economic diversification, social progress, and closer integration into national development, while ensuring security.
Since its return to China in 1999, Macao has evolved from a city once associated largely with casinos and gangster films into a vibrant international hub with a dynamic economy, a low crime rate and an increasingly comprehensive social welfare system. It now ranks among the world's wealthiest economies in terms of GDP per capita.
With the plan, the SAR government is proactively positioning Macao within the broader context of national development and actively implementing the relevant arrangements of the country's 15th Five-Year Plan (2026-2030), said Macao SAR Chief Executive Sam Hou Fai.
ECONOMIC DIVERSIFICATION
Economic diversification has remained a central theme throughout Macao's three five-year plans, from the first plan unveiled in 2016 to the latest one.
Sam said economic diversification is essential to sustaining Macao's long-term prosperity and stability and is a task the SAR government must tackle, no matter how difficult it may be.
According to Sam, the Macao SAR government will advance economic diversification through major projects and a government guidance fund to build Macao into a world tourism and leisure center and develop its priority industries, namely, big health, modern finance, high technology, exhibition and convention, as well as culture and sports.
The plan sets the target of raising the share of value added from non-gaming industries to around 60 percent of Macao's GDP by 2030.
Cheong Chok Man, director of the Policy Research and Regional Development Bureau under the Macao SAR government, said that setting such a target means Macao will need to intensify its efforts to achieve greater economic diversification.
Major projects aimed at promoting economic diversification during the period are expected to involve around 130 billion patacas (about 16.1 billion U.S. dollars) in budgeted investment.
For a small economy like Macao with a GDP of roughly 50 billion U.S. dollars in 2025, the investment represents a significant commitment, said Lao Chi Ngai, president of the Macao Economic Association.
BROADER INTEGRATION
The plan is designed to advance the high-quality development of the Guangdong-Macao In-Depth Cooperation Zone in Hengqin.
Located in Zhuhai, Guangdong Province, Hengqin is separated from Macao by a narrow stretch of water. The cooperation zone was established in 2021 to create new space for Macao's development.
This year marks a crucial period for the zone's second phase of development. The latest five-year plan calls for addressing challenges through reform and advancing deeper integration between Macao and Hengqin, with science and technology and education serving as key drivers.
The plan sets quantitative targets in areas including industrial diversification, cross-border flows of production factors, and the integrated provision and sharing of public services.
Richard W. Hu, dean of the Faculty of Social Sciences at the University of Macau, said the plan moves beyond integration in individual industries toward broader integration encompassing industries, people's livelihoods, talent and governance.
Hengqin is expected to develop into an integrated urban area that serves as an extension of Macao's industries and a vibrant cross-border community. In doing so, it could offer a landmark example of leveraging the institutional strengths of "one country, two systems" to foster closer regional synergy, Hu said.
SECURITY AS FOUNDATION
Alongside economic diversification and regional integration, the latest plan places security among its major priorities.
"Amid a complex and evolving international landscape, Macao faces potential challenges arising from a combination of traditional and non-traditional security risks," said Yin Yifen, director of the Social, Economic and Public Policy Research Center at Macao Polytechnic University.
He said the plan seeks to improve the legal framework and enforcement mechanisms for safeguarding national security, strengthen security governance in emerging areas such as cyberspace, data and artificial intelligence, and further develop smart policing.
It also places emphasis on national security education for young people.
"Making security an integral part of governance in the SAR will help lay a stronger foundation for economic diversification, improved livelihood and deeper integration between Macao and the mainland," Yin said.

B | 运维人员邢亮立即将此情况向电力调度控制中心、运维检修部等上级相关部门汇报，同时立即组织运维人员开展现场设备检查。         　　接到异常信息汇报后，国网供电公司立即组织相关专业成立党员突击队，开展设备异常情况诊断分析工作。18时30分，确认异常设备为220千伏II母线B相电压互感器本体存在异常隐患，随后申请设备停电开展设备诊断试验工作。直到6月18日凌晨2时，现场人员经过设备外观检查、全面试验，并结合设备厂家和省公司方面的专业意见，最终判断设备内部存在放电故障，不具备投运条件，需要及时进行更换处理。         　　220千伏团山子变电站主要担负着市区和周边工业企业输送电力任务，该变电站II母线B相电压互感器发生故障，直接影响站内保护设备的动作可靠性和计量装置的准确性。由于抢修需对220千伏团山子变电站II母线停电，该站I母线单独承担供电任务，若I母线跳闸将造成诸多重要用户全停，引发五级电网事件，所以这次抢修时间紧、涉及专业多、电网风险高。         　　为确保电网安全可靠运行以及重要客户和滨城百姓可靠供电，国网供电公司根据现场实际情况，迅速启动应急响应，积极沟通省公司专业部门和兄弟单位，协调备品设备并同步制定处理方案。

C | 与此同时，该公司变电检修工区、变电运行工区、二次检修工区、计量中心等多专业协调配合、迅速响应，于6月19日至20日期间进行为期两天的抢修作业，更换220千伏Ⅱ母线B相电压互感器，并按设备异常抢修方案要求开展各项试验和操作。         　　连日来，地区持续高温酷热。在连续两天的抢修作业现场，国网供电公司参与抢修各专业党员定战高温，挥汗如雨，干劲十足。他们有条不紊地指挥吊车和斗臂车，迅速拆装电压互感器，一丝不苟进行接线、紧固螺栓、设备调试试验等一项项作业内容。         　　“螺栓一定要紧固好，线夹要压紧，防止接触电阻过大，导致接点过热。”“保护绳要系好系紧，在斗臂车上面干活儿时刻不能放松，一定要注意安全。”在现场，变电检修专业经验丰富的郭玉琢老师傅反复叮嘱着检修人员。         　　据国网供电公司运维检修部专工朱兴鹏介绍，此次作业该公司共出动4个专业60人次，斗臂车、吊车大型车辆2辆，期间运行人员特巡值守16人次，开展设备特巡9次，更换电压互感器1组。         　　6月20日18时4分，随着新更换的电压互感器成功送电投入运行，此次抢修任务圆满完成，220千伏团山子变电站恢复全方式运行。

D |          　　在此次抢修作业中，国网供电公司各专业、各部门高效协调，积极配合，在最短时间内完成故障抢修投运任务，真正彰显了“葫电铁军”的责任担当和奉献精神，为迎峰度夏期间电网安全可靠供电提供了强有力的保障。
