美国众议院一个委员会本周推进一揽子有关科技出口管制法案。中国官方回应时说，将评估对中国利益的影响，誓言将坚决采取必要措施，维护中企合法权益。

美国众议院外交事务委员会星期三（4月22日）推进《硬件技术管制多边协调法案》（MATCH法案）等一揽子有关科技出口管制法案，旨在限制人工智能技术流向中国，并填补相关法律漏洞，防止中国获取先进半导体技术。

中国商务部星期六（26日）在官网回应时强调，中国一贯反对任何泛化国家安全、滥用出口管制的行为。相关法案如最终出台，将严重破坏国际经贸秩序，严重冲击全球半导体产业链供应链稳定。

商务部新闻发言人说：“中方将密切关注相关立法进程，认真评估对中方利益的影响，并将坚决采取必要措施，坚定维护中国企业合法正当权益。”

美国确认对福克兰群岛主权问题保持中立

美国国务院确认，美国在英国与阿根廷长期存在争议的福克兰群岛主权问题上持中立立场。

法新社报道，美国国务院发言人星期五（4月24日）说：“我们对福克兰群岛主权的立场始终保持中立。我们承认阿根廷和英国对此群岛存在相互冲突的主权主张。”

他也补充说，美国承认英国实际上拥有福克兰群岛的管辖权，但不在主权问题上选边站。

路透社报道，美国五角大楼在一封内部邮件中建议，重新审视美国对福克兰群岛主权的立场，以此惩罚英国对伊朗战争的立场。

英国首相斯塔默的发言人24日说，福克兰群岛的主权属于英国，并“向美国历届政府明确且始终如一地”表达这一立场。

福克兰群岛（阿根廷称马尔维纳斯群岛）目前由英国实际管辖和控制，属于英国海外领土，享有自治权。但阿根廷长期声称拥有福克兰群岛的主权。

1982年，阿根廷试图攻占福克兰群岛但未成功，英国和阿根廷爆发了一场短暂的战争，约650名阿根廷军人和255名英国军人阵亡。

美国已有13个州报告与家禽相关的沙门氏菌感染病例。

新华社报道，美国疾病控制与预防中心（CDC）星期四（4月23日）通报，来自13个州的34人因感染同一种沙门氏菌（Salmonella）菌株而患病，其中13人住院，目前尚无死亡病例报告。美疾控中心正与各州公共卫生部门开展联合调查。

美疾控中心说，鸡鸭等可家庭饲养的禽类即使看起来健康，也可能携带沙门氏菌。人接触家禽或家禽生活环境中的物品后，如未洗手便触碰口鼻或食物，可能导致沙门氏菌进入体内而感染。

美疾控中心提醒公众，在接触禽类、相关饲养用具或收集禽蛋后务必洗手；应将禽类及饲养用具置于室外，以防病菌传播；5岁以下儿童不应接触禽类及禽类活动区域的物品。

沙门氏菌广泛存在于家养和野生动物中，常通过受污染的食物感染人类。据美疾控中心介绍，人类感染沙门氏菌的症状通常包括腹泻、发烧、胃痉挛等，症状一般在接触病菌六小时至六天内出现。大多数患者可在四至七天内自愈，但儿童、老人、免疫力低下人群更易出现重症。

美国制裁涉采购伊朗石油中国独立炼油厂

在美国与伊朗艰难推动重启和平谈判之际，美国政府星期五（4月24日）宣布，对一家涉嫌购买价值数十亿美元（10亿美元约等于12.7亿新元）伊朗石油的中国独立炼油厂实施制裁。

美国财政部在官网发布的消息显示，此次被制裁的是恒力石化（大连）炼化有限公司。这家独立“茶壶”炼油厂被指是伊朗原油及石油产品的主要客户之一。

“茶壶”炼油厂是国际上对中国中小型民营炼油企业的统称。

美国财政部海外资产控制办公室还说，同时制裁约40家航运公司及船只，这些公司和船舶被指是伊朗“影子船队”的一部分。特朗普政府去年也曾对河北鑫海化工集团、山东寿光鲁清石化以及山东胜星化工等“茶壶”炼油厂企业实施制裁。

这些制裁措施给相关炼厂带来一定障碍，包括原油接收受阻，以及不得不以其他名称出售成品油。

“茶壶”炼油厂约占中国炼油总产能的四分之一，长期面临利润微薄甚至亏损的压力，近期又因中国国内需求疲软而进一步承压。

美国的制裁措施将冻结被制裁对象在美资产，并禁止美国人与相关企业开展业务。这已使一些规模较大的独立炼油厂对采购伊朗原油持更谨慎态度。

分析公司Kpler的2025年数据显示，中国购买了80%以上的伊朗出口石油。

不过，制裁问题专家认为，由于中国独立炼厂与美国金融体系联系有限，因此在一定程度上能削弱美国制裁的实际效果。他们认为，若进一步制裁协助相关交易的中国银行，才会对伊朗石油采购造成更大冲击。

US appeals court allows Texas to enforce migrant arrest law

• Appeals court overturns injunction, allowing Texas to enforce SB4 migrant arrest law
• Immigrant rights groups and El Paso challenge the law in court
• Dissenting judges say federal law pre-empts Texas immigration enforcement

April 24 (Reuters) – A federal appeals court on Friday cleared the way for Texas authorities to enforce a Republican-backed state law that would let them arrest and prosecute people suspected of illegally crossing the U.S.-Mexico border.

A 10-7 panel of the New Orleans-based 5th U.S. Circuit Court of Appeals overturned a 2024 injunction that had blocked enforcement of the law, which former Democratic President Joe Biden’s administration had gone to court to challenge.

Republican President Donald Trump’s administration dropped the federal government’s case, but the Texas law known as SB4 continued to be challenged by immigrant-rights groups Las Americas Immigrant Advocacy Center and American Gateways and the city of El Paso.

That law, which Texas Governor Greg Abbott signed in December 2023, would make it a state crime to illegally enter or re-enter Texas from a foreign country and would empower state judges to order that violators leave the United States, with prison sentences up to 20 years for those who refuse to comply.

After a judge in February 2024 issued a preliminary injunction blocking the law, the case arrived at the U.S. Supreme Court, which briefly allowed the law to take effect before the 5th Circuit within hours halted it pending further review.

A 2-1 panel of the 5th Circuit in July 2025 upheld the injunction, saying the state law would interfere with the federal government’s ability to enforce U.S. immigration laws.

But the full appeals court, among the most conservative in the nation, agreed to reconsider the case at the urging of Republican Texas Attorney General Ken Paxton.

U.S. Circuit Judge Jerry Smith in Friday’s ruling said that just because the legal advocacy groups voluntarily opted to increase representation of immigrants adversely affected by the law did not mean they had standing to challenge it.

“When enterprising plaintiffs repackage a generalized grievance as an ‘injury,’ courts should rightly exercise caution,” Smith wrote in an opinion joined by all but two of the court’s Republican-appointed judges.

Paxton in a statement hailed the ruling. “Texas’s right to arrest illegals, protect our citizens, and enforce immigration law is fundamental,” he said.

The plaintiffs’ lawyers did not immediately respond to requests for comment.

Seven judges dissented, including U.S. Circuit Judge Priscilla Richman, an appointee of Republican President George W. Bush who said that under a controlling 2012 precedent of the U.S. Supreme Court, Texas’ law was trumped by federal law.

“Texas cannot enact its own immigration regime,” she wrote.

Naval escorts will likely be needed when Strait of Hormuz reopens, Chevron CEO says

April 24, 2026 5:57 PM EDT / CBS News

By Caitlin Yilek

Caitlin Yilek is a politics reporter at CBSNews.com, based in Washington, D.C. She previously worked for the Washington Examiner and The Hill, and was a member of the 2022 Paul Miller Washington Reporting Fellowship with the National Press Foundation.

Washington — Chevron’s chief executive said it’s likely that the U.S. Navy may need to escort commercial vessels through the Strait of Hormuz once it reopens in order to ensure a level of security.

The standoff over the strait has intensified amid Iran’s threats against the critical channel and a U.S. blockade on Iranian ports, effectively closing it. The tensions have led to several maritime incidents in recent days.

Asked Thursday by “Face the Nation” moderator Margaret Brennan what Chevron would need to see to feel confident to send a ship through the strait, CEO Mike Wirth said, “we’d have to believe that our people on the ship will be safe, the cargo will be safe, and they can be transited with with a high degree of confidence.”

Wirth said the decision would be made “in collaboration” with the U.S. Navy and other military organizations around the world.

“I think in the early days, it’s very likely that you could see naval escorts, because I think some of the risks are not just mines that could be placed in the strait, but they could be also risks that could come from the land in other forms,” Wirth said. “So I think having the Navy with those ships that make the first transit would provide a higher degree of confidence than if there were to be something [that] happened, that you’d have some measure of defense.”

Since the start of the war, President Trump has sent conflicting messages about securing the key waterway, through which about a fifth of the world’s oil travels through. On Thursday, Mr. Trump said U.S. minesweepers were clearing the strait and directed the U.S. Navy to “shoot and kill” Iranian boats placing mines in the strait.

WASHINGTON, April 24 – The Democratic governor of Maine, Janet Mills, vetoed a bill that would have made it the first U.S. state to impose a moratorium on large new data centers, saying the move would ​have disrupted jobs tied to a project already underway.

Maine lawmakers had approved the bill last week, in what was ‌seen as a test case amid growing local opposition to large facilities powering Washington’s AI race against Beijing.

The Maine bill aimed to freeze approvals for data centers requiring more than 20 megawatts of power until October 2027, while a state-appointed council analyzes their impact on the local grid, electricity ​bills, air and water.

A dozen other states are considering a moratorium on data centers. Here is the most ​recent list of U.S. states that have had bills targeting data centers introduced in their ⁠legislatures.

State Bill Description
Georgia HB 1012 Bars counties and cities from issuing permits, licenses or certificates for the construction or development of new data centers ​until March 1, 2027, with an exception for approvals issued before July 1, 2026.
Maryland HB 120 Prohibits the construction of new data ​centers unless the General Assembly enacts legislation related to co-location with new or existing power generation (including natural gas, nuclear or small modular reactors, or SMRs).
Michigan House Resolution 240 A statewide moratorium that calls for a temporary pause on state incentives for data centers.
New Hampshire HB 1265 Prohibits the construction of ​a new data center anywhere in the state for one year from the act’s effective date and forms a ​committee to study the environmental impacts of data centers.
Minnesota SF 4298 Bars state and local governments from issuing permits for data centers until a year ‌after ⁠the Public Utility Commission submits a report on data center development scenarios in the state.
New York S9144 Imposes a statewide moratorium on permits for new data centers and directs the Public Service Commission to come up with a plan to minimize their impact on electricity and gas rates.
Oklahoma SB 1488 Imposes a moratorium on building new data centers until November 1, 2029, and tasks ​the Oklahoma Corporation Commission with studying ​the impact on water ⁠supply, utility rates, property values and site locations.
South Carolina H 5286 Bars state and local governments from granting permits, approvals or incentives for new data centers until January 1, 2028.
South Dakota SB 232 / ​HB 1301 Sets a one-year moratorium on the construction or expansion of hyperscale data centers. ​House bill imposes ⁠a moratorium while also addressing cost/risk allocation tied to electricity usage by data centers.
Vermont S 205 Creates a temporary moratorium through July 2030 while regulators study impacts and recommend a regulatory framework.
Virginia HB 1515 Bars localities from granting final approvals for rezonings/special permits for new data ⁠centers until ​specified grid-interconnection conditions are met.
Wisconsin LRB-6377/1 Creates a statewide moratorium on data centers by ​prohibiting the operation of a data center unless the legislature first enacts rules — such as a statewide planning authority and explicit bans on shifting data ​center energy and water costs onto residential customers.
