Washington/Tehran: Tensions between the United States and Iran have intensified again as both sides exchanged defiant messages ahead of Washington’s planned announcement of a new round of economic sanctions against Tehran.
The United States is expected to unveil fresh sanctions on Monday, with the measures aimed at increasing economic pressure on Iran and potentially affecting countries and companies that continue doing business with Tehran. China, which remains the biggest buyer of Iranian oil exports, is expected to be a major focus of the new measures.
US Prepares Tougher Sanctions on Iran
US Treasury Secretary Scott Bessent has said Washington is preparing what he described as its toughest sanctions yet against Iran.
Details of the measures are expected to be announced during a press conference on Monday. The sanctions are intended to further restrict Iran’s access to international markets and reduce revenue generated from its oil exports.
The United States has been increasing economic and military pressure on Tehran amid the continuing confrontation between Iran and the US and its regional allies.
Washington has also focused heavily on restricting Iran’s ability to export crude oil, one of the country’s most important sources of foreign revenue.
China Could Be Major Focus of New Measures
China is particularly important to Iran’s oil trade.
According to Reuters, China purchases more than 80% of Iran’s exported oil shipped internationally, making Chinese buyers a critical source of revenue for Tehran.
US officials have urged Beijing to cooperate with Washington’s efforts to isolate Iran economically.
China, however, has opposed unilateral sanctions and has argued that diplomatic negotiations should be used to resolve disputes instead of economic pressure.
Any measures targeting companies involved in buying or transporting Iranian oil could therefore have implications beyond Iran and potentially affect global energy markets.
Iran Rejects US Pressure
Iranian officials have strongly criticised Washington’s approach and rejected the threat of additional sanctions.
Tehran has argued that the measures violate international law and has maintained that Iran will continue defending its national and economic interests despite US pressure.
Iranian officials have also signalled that the country remains prepared to respond militarily if necessary while continuing to leave open the possibility of diplomacy under acceptable conditions.
The tough rhetoric from both sides highlights how limited diplomatic progress remains despite months of confrontation.
Iranian Oil Exports Face Growing Pressure
Iran’s oil industry has already been affected significantly by restrictions and disruptions.
Reuters reported that Iranian crude offers to Chinese buyers have fallen sharply, while tighter supplies have pushed up prices for some Iranian barrels.
Iranian shipments reportedly dropped to around 534,000 barrels per day in August, compared with an average of approximately 1.4 million barrels per day in 2025.
The decline illustrates the growing pressure on Tehran’s ability to generate revenue through energy exports.
Strait of Hormuz Remains a Major Concern
The continuing confrontation has also raised concerns over the Strait of Hormuz, one of the world’s most strategically important routes for oil and gas shipments.
Shipping activity through the region has been significantly disrupted amid the conflict, increasing uncertainty for energy markets and international trade.
Only limited numbers of vessels have been able to move through the area, with some Iraqi oil tankers reportedly receiving special permission from Iran to pass.
Any further escalation around the Strait of Hormuz could have a major impact on international crude oil prices and global supply chains.
Diplomatic Breakthrough Still Uncertain
Despite occasional signals that diplomacy remains possible, there has been little visible progress toward a broader agreement.
US President Donald Trump said earlier this week that no formal talks with Iran were taking place or scheduled, highlighting the continuing uncertainty over negotiations.
With Washington preparing new economic sanctions and Tehran publicly rejecting American pressure, attention is now focused on Monday’s announcement and how Iran, China and other countries affected by the measures will respond.
The next round of sanctions could become another major turning point in the continuing US-Iran confrontation, with consequences for regional security, global oil markets and international diplomacy.
