As military strikes and diplomatic negotiations have both failed to bring an early end to the roughly six‑month‑old US-Iran conflict, Washington rolled out new sanctions against Tehran on Monday local time intended to further strangle its economy. Iran, for its part, has vowed a tougher pushback.
In a news conference on Monday, Treasury Secretary Scott Bessent threatened new sanctions on countries refusing to cut economic ties with Iran, following recent rhetoric from Washington threatening an "economic D-Day" for Iran. 
Meanwhile, the Office of Foreign Assets Control (OFAC) under the US Treasury announced secondary sanctions on nearly 60 entities, individuals, and vessels in multiple jurisdictions which, according to the US' claims, enable Iran's activities, including so-called nuclear and missile technology procurement, cyber operations, and oil-revenue generation networks.
According to Reuters, those sanctions targeted businesses in China, the UAE, Singapore and several other countries, including a cooking-oil refinery in France, but did not include any of the Chinese financial institutions suspected of facilitating Iran's oil trade.
In response to US Treasury Secretary Scott Bessent laying out plans for economic asphyxiation of Iran, expanding Washington's secondary sanction threats and warning of dire consequences for countries that do not join the campaign, Chinese Foreign Ministry spokesperson Lin Jian said at a press briefing on Tuesday that China has made clear on many occasions its firm opposition to illicit unilateral sanctions that have no basis in international law or the authorization of the UN Security Council. 
"Economic warfare and maximum pressure provide no solution. On the contrary, they only serve to fuel tensions and lead to risk spillover, which will disrupt the global economic and financial order, and harm the legitimate rights and interests of other countries," the spokesperson said. 
The pressing task is to facilitate the deescalation of the situation and return to dialogue and negotiation as soon as possible, Lin said, adding that China will do everything necessary to firmly safeguard its rights and interests, Lin added. Lin also said China's cooperation with Iran is conducted within the framework of international law, thus should not be disrupted.
When asked whether China has received any such timeline, as the US stated it would give countries a timeline on when to shut down the actions that it has identified, and how China intends to respond to the relevant announcements by the US Treasury involving China-based entities and individuals, Chinese Foreign Ministry spokesperson Lin Jian stated on Tuesday that China is closely following the developments, and will do everything necessary to firmly safeguard our rights and interests.
In May this year, China's Ministry of Commerce issued a blocking ban prohibiting any recognition, enforcement or compliance with US sanctions imposed on five Chinese companies on the grounds of their alleged involvement in Iranian petroleum transactions.
Relying on its financial hegemony and long‑arm jurisdiction, the US enforces unilateral sanctions with no basis in international law. Such measures severely undermine fundamental consensus for international trade and erode the existing international order, Zhou Mi, senior research fellow at the Chinese Academy of International Trade and Economic Cooperation, told the Global Times on Tuesday.
In essence, Washington is imposing its Iran‑focused policies to enterprises across the globe, compelling third‑party actors to fall in line with its diplomatic objectives, Zhou noted.
The latest sanctions would affect a broader range of countries, industries and firms. They will not only draw wider opposition from the international community, but also boomerang on the interests of US‑owned enterprises, he added. 
Fewer levers left 
"We are launching an economic onslaught against Iran's financial connections around the globe," Bessent claimed at a press conference. "Our objective is to sever every economic lifeline" that sustains the country, he said, according to a Treasury release. 
The US Treasury Department said in a release that the new sectoral sanctions determinations target five critical sectors - digital assets, technology, gold, aviation and shipping - that the US claimed Iran has relied on to support its economy.
US Treasury claimed that "any entity that facilitates money laundering or sanctions evasion on behalf of Iran risks being cut off from the US financial system."
OFAC also suspended several general licenses that previously authorized certain remittance payments to Iran and Iranian access to the US cultural and academic system. The office also issued additional guidance on the so-called sanctions risks of bowing to Iranian demands related to shipping in the Strait of Hormuz.
Mohammad Mokhber, an aide to Supreme Leader Mojtaba Khamenei, said in an X post on Monday that Iran's response to US sanctions and pressure will be "more decisive than before."
Iranian Economy Minister Ali Madanizadeh said that Tehran "is and was ready," with a two-year plan to counter Washington's new sanctions. He told state television that "it seems they wished to suffer yet another defeat," per an AFP report. 
Iranian Parliament Speaker Mohammad Bagher Ghalibaf responded in an X post that "the Americans know no one will believe their nonsense," noting that the US is not in a position economically to restrict its relations with other countries. 
Alan Eyre, a distinguished diplomatic fellow at the Middle East Institute, told NBC News that after six months of combat, the US government "has few remaining levers it can use to convince Iran's major trading partners to materially reduce their economic ties."
While Washington's maximum‑pressure campaign may deliver short‑term shocks to Iran's economy, it can hardly "strangle" the country completely, said Liu Zhongmin, a professor at the Middle East Studies Institute of Shanghai International Studies University.
He added that Iran's economic resilience cannot be underestimated. Having borne decades of crippling sanctions from the US and Western nations, Tehran has built substantial experience in sanction‑busting and developed coping mechanisms ranging from basic‑industry self‑reliance and regional trade networks to oil‑for‑goods swaps and non‑US dollar‑denominated trade. Furthermore, the Strait of Hormuz remains a source of strategic leverage for Iran to push back against US pressure.
The expert said that Tehran and Washington are encountering "a battle of wills," and Iran believes the economic costs the US would suffer from a Hormuz blockade would outweigh the damage inflicted on Iran by sanctions.
Washington's "economic strangulation" policy risks ending in failure unless it yields short‑term outcomes, particularly securing the opening of the Strait of Hormuz, Liu added. 
Self-created dilemma
As the US ramps up pressure on Iran, Americans are growing averse to a protracted war.
According to a Reuters/Ipsos poll that closed on Monday, US ‌public approval of the war with Iran fell to its lowest level since the conflict's early days, with just 31 percent of Americans supporting US military action.
On June 18, the US and Iran signed an MoU, under which the two were scheduled to hold negotiations within a period of 60 days, which ended on August 17, to reach a final agreement. However, the talks' fate remains unclear following renewed escalation between the two countries.
Iranian political analyst Mostafa Khoshcheschm told Al Jazeera that the new US sanctions intended to create an "economic onslaught" were a "political show" of intimidation. 
Liu said that by resorting to an "economic strangulation" tactic after miring itself in a fruitless military quagmire over Iran, the US has laid bare its practical predicament and strategic dilemma, and seemingly running out of cards.
Citing sources, CNN reported earlier this month that the US military has exhausted nearly 80 percent of its interceptors for a key missile defense system as senior US military commanders are warning that the Pentagon's munitions stockpile is "dangerously low."
Faced with depleted ammunition stockpiles and insufficient military‑industrial capacity, and amid growing domestic criticism of its Middle East policy, the White House has opted for tough economic measures against Iran, Liu said. "Less costly than military coercion, such moves help Washington strike a tough posture before voters and shun political risks from further military escalation," said the expert.
There is, however, an increasingly obvious paradox in Washington's economic warfare against Iran: the tighter the sanctions, the tighter global energy supplies become, and the higher costs borne by American consumers and businesses, the expert added. 
。如此高的血脂，诱发了患者急性胰腺炎的发作，引起患者腹痛、恶心、呕吐不止而入院就医，病情危重。　　尽快将甘油三酯降至正常是延缓脂源性胰腺炎进展的关键。而双重滤过血浆置换能够快速有效地清除体内的甘油三酯。

C | 该院重症医学科团队决定立即对其开展双重滤过血浆置换治疗。　　从患者体内置换出的如“牛奶”般的甘油三酯。▲图源：深圳新闻网 视频截图　　该名患者在通过双重滤过血浆置换后，甘油三酯水平由157mmol/L迅速下降至16mmol/L。经过及时的治疗，患者病情逐渐平稳，脱离生命危险。

D | 　　其实，“牛奶血”并不少见！广州日报近几年也有相似案例报道：　　38岁的阿坤（化名）已有13年糖尿病史，但认为自己还年轻，经常没有节制地胡吃海喝。某晚大吃一顿海鲜加熬夜喝酒吃烧烤后，隔天阿坤突然瘫倒在沙发上。紧急送医后，医生发现阿坤的血浆跟酸奶一样，甘油三酯水平超出正常人16倍！医生推断，阿坤是长期高血脂症导致颅内血管动脉硬化堵塞，最终引起中风。　　2023年，不到30岁就有代谢紊乱综合征的阿文（化名），在一顿大快朵颐之后，她突然感觉上腹剧痛，这种痛还逐渐蔓延至腰背。

E | 医生判断，阿文很可能是高脂血症引起的急性胰腺炎。　　阿文被迅速转诊到广医五院。化验结果显示，阿文血液中含有很高的脂肪成分，抽出来的4000毫升血通过净化治疗后，分离出一袋200毫升的血脂及有害物质，像“黄油”一般。　　什么是“牛奶血”？▲图源网络　　在人体血液中，存在着各种脂蛋白，其中有一种外源性脂蛋白乳糜微粒，主要来源于食物脂肪中，其含有大量的甘油三酯。　　如果甘油三酯在血液中的浓度超过11.3毫摩尔/升，血浆就会呈现出乳白色，也叫乳糜血。平时饮食油腻的人，容易出现乳糜血。　　以上几个案例都有一个共同点：甘油三酯严重超标。　　医生提醒：　　人体的甘油三酯畸高，特别容易导致肾衰、肝衰、肺栓塞，以及心梗、脑梗和四肢坏疽等致死性疾病。

F | 　　一旦血液变得黏稠，流速就会变慢，油脂沉淀到血管内膜上就容易引发血管硬化，不断加剧的血管硬化，就会导致血流梗阻。血流梗到哪里，哪个脏器就缺血、衰竭。　　医生提醒：　　肥胖、久坐不运动、吸烟、酗酒、暴饮暴食、偏食、饮食不规律以及精神紧张等都是引起血脂异常的高危因素。　　如何才能有效降低甘油三酯呢？　　一方面要清淡饮食。一些肉类及油炸、烘焙食品，往往含有不易消化的饱和脂肪酸和反式脂肪酸，是导致甘油三酯升高的原因之一，应该尽量少吃；而蔬菜水果、杂粮类富含膳食纤维的食物可以多吃。

G | 爱吃肉的人，可以选择禽肉、鱼肉等，特别是深海鱼肉。深海鱼肉含有的DHA和EPA，有利于肠道脂质排泄，是降低甘油三酯的好食材。　　另一方面要加强运动。坚持锻炼，可以有效改善甘油三酯代谢，往往会起到降低甘油三酯的效果。另外，还应该注意戒烟限酒，控制体重，少熬夜。　　在生活调理的同时，也可以考虑服用药物来控制甘油三酯。目前较为常见的控制甘油三酯的药物包括贝特类药物，如苯扎贝特、非诺贝特等，苯扎贝特尤其适合糖尿病伴高甘油三酯血症的患者。

H | 药物治疗也需根据患者的身体情况而定，用药期间注意监测肝功能，如果与他汀类药物联用，则更要注意肝功能损伤风险。
