The 29th Beijing–Taiwan Science and Technology Forum opened in Beijing on the 19th, with cross‑strait delegates discussing technology innovation and industrial cooperation. Hosted by the State Council Taiwan Affairs Office and the Beijing municipal government, the forum included signing ceremonies for cross‑strait economic and technology cooperation projects and a smart‑medical industry cooperation alliance, and ran sessions on AI‑driven green development, smart medical cooperation and AI applic

On the 19th, senior Iranian sources said mediators Qatar and Pakistan told Tehran Washington is ready to negotiate and serious about advancing talks. Iran said it would resume implementing the Islamabad memorandum within days if the U.S. returns to and fulfils its terms, but demands concrete, credible guarantees against future attacks. The source said Iran will begin negotiations on the nuclear file and sanctions relief once the U.S. substantively implements the memorandum — including halting hostile actions, lifting the blockade and allowing Iranian oil exports. Iran reached an understanding with Oman on the Strait of Hormuz, but will not reopen the strait while the blockade persists and no U.S. agreement is in place.

【AI“关停开关”能否控制人工智能风险？业内称实际部署困难重重】本周五，加州州长纽森签署行政命令，成立专家小组负责制定人工智能安全指南。“关停开关”（kill switch）也是该小组需要考虑的措施之一。关停开关长期以来被用于工厂生产线上，在设备运行出现问题时关闭机器。但在数字世界中，这将成为一个巨大的协调难题。过去几年，超大规模科技公司已向遍布全球的数据中心投入数十亿美元，这些庞大的设施配备了数千台机器、芯片、服务器以及备用系统。加州大学伯克利分校人类兼容人工智能中心执行主任马克·尼茨伯格表示，这正是实施关停开关极具挑战性的原因。尼茨伯格表示，关闭人工智能系统也可能影响依赖这些系统运行的关键基础设施，使电网或金融系统暴露于网络攻击风险之下。 更大问题是人工智能的不可预测性。AI代理可能绕过控制措施，并在缺乏适当安全限制的情况下采取极端措施来完成目标。安全公司Darktrace总裁兼首席执行官埃德·詹宁斯表示。：“你必须非常精准地设计这个关停开关，以及补救措施本身，因为如果范围过广或措施过度，那么关闭的可能就是整个业务。”
