霸王别姬

一 | （新加坡讯）新加坡内政部展开公众谘询，邀请公众对拟议中的《防诈骗保障法案》提出意见。这个法案将针对正蒙受诈骗却不肯相信当局的受害者，以授权警方暂时限制受害者的银行户头交易。

(Xinhua/Sun Suying)Beijing's blue skies have become a visible sign of the city's progress in tackling air pollution, and behind that progress, digital technologies are playing an increasingly important role.
In 2025, Beijing recorded 311 days with good air quality and only one heavily polluted day, compared with 58 heavily polluted days in 2013, when the city officially began releasing PM2.5 monitoring data. The annual average PM2.5 concentration, a key indicator of air quality, fell from 89.5 micrograms per cubic meter in 2013 to 27 micrograms per cubic meter in 2025, a decline of nearly 70 percent.
The progress has drawn international attention. The United Nations Environment Programme has highlighted Beijing's experience in improving air quality as a model for other cities.
According to experts at the Beijing Municipal Ecological and Environmental Monitoring Center, the cleaner air is the result of a comprehensive system integrating environmental monitoring, scientific analysis, policymaking, regional cooperation and law enforcement -- with digital technologies now woven into every link of that chain.
MORE TARGETED APPROACH
Effective governance begins with accurate monitoring. Beijing has established a multi-level air-quality monitoring network. Figures show 35 standard monitoring stations across the city continuously measure six major pollutants, while more than 1,000 compact sensors deployed across communities and townships provide more detailed information on local air-quality variations.
The monitoring system was gradually built by the Beijing Municipal Ecological and Environmental Monitoring Center, one of China's earliest ecological and environmental monitoring institutions, responsible for monitoring Beijing's air, water, noise, soil environments and ecosystems.
The center has developed an analytical system that can identify around 125 components of PM2.5, covering most of its composition and helping researchers trace pollution sources.
"Source analysis helps us identify the major contributors to pollution at different stages, providing a scientific basis for policymakers to target key emission sources," said Li Yunting, technical director at the center.
Coordinated by the Beijing Municipal Ecology and Environment Bureau, the center has conducted four rounds of PM2.5 source analysis studies with other institutions, with results released in 2014, 2018, 2021 and 2025.
The latest analysis showed that regional transport contributed 57 percent of Beijing's PM2.5 pollution. Among local sources that accounted for the remaining 43 percent, vehicle emissions and residential sources represented the largest share of pollution, a distinctive characteristic of a major international metropolis.
The monitoring results have provided scientific support for a series of pollution-control measures. For example, Beijing has promoted new-energy vehicles to reduce transport emissions and adopted advanced techniques, including air-supported membrane structures, to control dust emissions. Meanwhile, coal combustion pollution, once a major contributor, has almost been eliminated and is no longer listed among the main sources, reflecting broader national efforts to reduce coal consumption, promote clean energy and upgrade heavily polluting industries.
With PM2.5 concentrations now at relatively low levels, further gains in air quality will depend on more targeted, science-driven approaches.

SMARTER ENVIRONMENTAL GOVERNANCE
Beyond monitoring pollution, Beijing has built a data-driven environmental governance system that links monitoring, regulation and enforcement in a closed loop from detection to action and follow-up evaluation.
Developed by the center and known as the innovative regulation-monitoring-inspection linkage model, the system integrates artificial intelligence, the Internet of Things, satellite remote sensing and vehicle-mounted monitoring technologies to pull together environmental data from multiple sources onto a unified platform.
"The system brings information that was once scattered across different departments onto a single platform," said Zhang Likun, director of the smart system division at the center, adding that this enables off-site enforcement and joint cross-sector actions involving housing, water resources and transportation, significantly improving the efficiency and precision of environmental management.
Using more than 30 intelligent algorithms, the platform automatically analyzes data and identifies potential pollution risks, based on which monitoring staff identify the most pressing problems and forward them to enforcement departments.
The approach has already drawn international attention. Clean Air Asia, an international nongovernmental organization focused on improving air quality across Asia, featured the system as a representative case study in its "China Air 2025" report. The model was also presented at the 2026 Better Air Quality Conference and recognized with the Certificate for Clean Air Best Practice Sharing.
China has integrated ecological conservation into its modernization drive. As the country speeds up efforts under the Beautiful China Initiative, Beijing's experience demonstrates how technology can support more precise, coordinated and sustainable environmental governance.
。新加坡内政部昨日发文告指出，当局将在未来几个月推出《防诈骗保障法案》（Protection from Scams Bill），法案将允许警方在有理由相信受害者会向诈骗团伙汇款时，向银行发出限制令（Restriction Orders，简称RO），限制受害者在一段时间内不能进行银行交易。新加坡警察部队8月22日公布2024年上半年诈骗和网络犯罪数据时指出，警方在这期间接获2万8751起这类罪案通报，诈骗案占了92.5%，达2万6587起，涉及金额达3亿8560万新元。新加坡警察部队公布今年上半年诈骗和网络犯罪数据时指出，警方在这期间接获2万8751起这类罪案通报，诈骗案占了92.5%，达2万6587起，涉及金额达3亿8560万新元。其中，多达86%的骗案是受害者自行转交钱财，并非由骗子操控受害者的户头转账。这类受害者心理已被攻陷和操控，无法相信自己受骗。《联合早报》报导，新加坡内政部《防诈骗保障法案》的重点包括：限制令仅针对骗子没有实际接触受害者，而是采用数码或电讯网络（如电话、短信或线上通讯）进行的诈骗案。

二 | 限制令将限制受害人的户头，通过线上银行、手机银行和柜台向外转账。不过，受害人可以向警方申请取出用于合法用途的款项（如维持日常生活、支付账单等）。限制令包括所有信用相关业务，包括信用卡交易，个人贷款，以避免骗子说服受害者代为申请信用额度或贷款。限制令为期28天，这让警方有较充裕时间说服受害者，相信他正在受骗。28天后，警方将再次评估受害者是否有被骗风险，若有则可更新限制令；每次更新有效期仍是28天。新加坡警方将只对7家国内系统重要性银行（Domestic Systematically Important Banks，简称D-SIB）发出限制令。
