一 | President Joe Biden is expected to roll back some Trump-era tariffs on Chinese imports as early as next week, according to insiders cited by The Wall Street Journal.,The decision, which could include a pause on tariffs on consumer goods ranging from clothing to school supplies, would likely be complemented by a broader policy allowing importers to request tariff waivers, added the report.,The decision is believed to be prompted by the need to address sky-rocketing inflation, which rose unexpectedly last month to a fresh four-decade high of 8.6%, according to the US Labor Department.,However, the move will attempt to strike a balance between cutting consumer costs while maintaining pressure on Beijing, stated the publication.,The timing of the reported announcement is linked to a mandatory four-year statutory review of tariffs set in place under then-President Donald Trump by the Office of the US Trade Representative (USTR). It issued a Federal Register notice in May to initiate the first step of the process to determine whether China tariffs “issued pursuant to Section 301 of the Trade Act of 1974” should be continued beyond the 4-year mark since their implementation.,Thus, claimed the report, the Biden administration will be provided with an opportunity to ‘calibrate its policy’ before the comment period for businesses and others who have benefited from the tariffs closes on July 5.,‘Split’ Over China Tariff,Joe Biden’s decision regarding China tariffs has been delayed up until now due to deep divisions within his own administration on this issue, according to WH officials and trade experts cited by the outlet.,US Treasury Secretary Janet Yellen in June revealed that the administration was looking at ways to ‘reconfigure' the tariffs to help curb inflation, adding that some of the restrictions inherited from the administration of the 45th POTUS were not ‘strategic’ and failed to address China’s ‘unfair trade practices.’,“Reconfiguring some of those tariffs so they make more sense and reducing unnecessary burdens is something that’s under consideration,” Ms. Yellen said in an interview with ABC News on June 19.,Still earlier, on June 8 Yellen told the House Ways and Means Committee hearing she expected the Biden administration to have additional information on its plans ‘in the coming weeks.’,“I think some reductions may be warranted,” Yellen said of the tariffs, claiming that the cost of certain duties on China ended up being paid by Americans. Her stance has been reportedly supported by Commerce Secretary Gina Raimondo.,Scholar: Biden's Plan to Lift China Tariffs Shows US Can't Take on Beijing and Moscow at Once24 June, 16:21 GMT,Proponents of tariff slashing believe that it could signal Biden’s resolve to fight inflation and boost the Democratic president’s plummeting approval rating ahead of the November midterms.,However, opposing a paring back of the tariffs are US Trade Representative Katherine Tai and National security adviser Jake Sullivan, reported WSJ. Tai has repeatedly defended the tariffs as a useful tool for achieving concessions from China.,“The China tariffs are, in my view, a significant piece of leverage, and a trade negotiator never walks away from leverage,” Tai told a Senate subcommittee meeting on June 22.,According to skeptics, a mulled tariff cut should be complemented by specific measures. The suggested options ostensibly include raising tariffs on strategic items such as industrial machinery and transportation equipment, while lowering duties on consumer goods.,Furthermore, tariffs on a new set of products could be derived from a fresh US probe under Section 301 of the Trade Act focusing on China’s industrial subsidies on high-tech items, stated the report.,However, economists doubt that easing Chinese tariffs would have a dramatic impact on inflation.,Leading US Unions Urge Biden Administration Not to Ease Tariffs on Chinese Goods7 June, 12:23 GMT,Peterson Institute for International Economics analysts Megan Hogan and Yilin Wang were cited as saying that removing tariffs on Chinese imports could bring down the consumer-price index inflation by no more than a marginal 0.26 percentage points. However, subsequently, “as US corporations trim their markups to compete with imports,” that might result in a 1-percentage-point reduction in inflation, experts added.,In his trade war with China over its purportedly unfair trading practices, former President Donald Trump imposed over four rounds of levies between July 2018 and September 2019. Targeting Chinese imports worth an estimated $370 billion, they ranged from 7.5% to 25%.,Trump’s actions were based on the findings of a Section 301 investigation into China’s practices related to technology transfer and intellectual property.,Despite the US and China penning a trade deal in 2020, Washington had kept intact most levies on Chinese imports ostensibly to ensure compliance with the accord’s provisions. Beijing has argued that the tariffs hurt both countries.,“With inflation rates running high across the globe, the U.S. needs to lift all the additional tariffs imposed on China, as this will serve the interests of businesses and consumers and benefit both countries and the world at large,” Chinese Foreign Ministry spokesman Wang Wenbin said at a June 15 press conference.。 一家美国公司遭到美国AI攻击，而提供保护的竟是一款中国人工智能工具。 AI工具平台Hugging Face上周遭到OpenAI模型攻击。鉴于当前关于美国公司使用中国AI产品存在风险的警告层出不穷，这一事件的披露或许会带来一个令人惊讶的结论。 Hugging Face上周就已披露此次攻击，当时尚不知晓OpenAI的模型就是元凶。
二 | 直到周二，OpenAI才承认自己造成了此次攻击。 OpenAI表示，在一次限制网络访问的内部评估中，模型发现了OpenAI研究环境与Hugging Face生产基础设施中的漏洞。模型借此连上互联网并获取了测试答案，换言之，它在评估中作弊了。 OpenAI在声明中表示：“在沙盒测试环境中运行时，我们的模型消耗了大量推理算力，试图寻找连接开放互联网访问权限的方法，以求解决评估问题。为了获取访问权限，这些模型发现并利用了包注册表缓存代理中的一个零日漏洞（我们目前已负责任地向供应商披露了该漏洞）。凭借这一权限，模型在研究测试环境中执行了一系列权限提升和横向移动操作，直到触及一个具备互联网访问权限的节点。” “该模型搜索并成功找到了获取机密信息的方法，以便利用这些信息在评估中作弊。在其中一个案例中，模型将多个攻击向量串联起来，包括利用窃取的凭证和零日漏洞，在Hugging Face服务器上找到了一条远程代码执行路径。” 然而，Hugging Face采取的应对措施是求助于一款名为GLM 5.2的中国AI模型，该模型由智谱（Z.AI）开发。 Hugging Face在声明中表示：“在启动日志分析时，我们首先使用了商业API背后的前沿模型。但这并未奏效：分析工作需要提交大量真实的攻击指令、漏洞利用载荷以及C2痕迹，而这些请求全被提供商的安全护栏拦截了，因为这些护栏根本无法区分事件响应人员与攻击者。因此，我们在自己的基础设施上，改用开放权重模型GLM 5.2进行了取证分析。这还带来了另一个好处：没有任何攻击者数据，也没有其引用的任何凭证离开过我们的环境。” 美媒表示，此次攻击对政策和市场的影响尚不明朗。尽管特朗普政府近日讨论了封禁中国模型的可能举措，财政部长贝森特甚至将美国企业使用这些模型比作使用赃物，但眼下只有中国模型能提供用户所需的那种自由访问权限。 Hugging Face联合创始人托马斯·沃尔夫在X平台上发帖称：“当一个前沿模型对你发起攻击，并在你的基础设施内部横向移动时，防御人员需要在数小时甚至数分钟内获得对接近前沿工具的广泛访问权限，而不是被引导至一个封闭且需经审核的模型访问申请程序。” 本文系观察者网独家稿件，未经授权，不得转载。
