Iran Deal Tested: Tehran Ties Inspections to Sanctions

For a country that builds its energy stability on imports and watches every tremor in oil supply closely, what is unfolding this week between Washington and Tehran is not a distant story. The price of crude, the supply routes through the Persian Gulf and the overall balance in the Middle East feed directly into the European market, and therefore into the prices felt at Serbian fuel pumps. A week after signing the truce, the two sides are openly disputing the most basic question of all: what that document actually means.

At the centre of the dispute is access for inspectors of the International Atomic Energy Agency to Iran’s nuclear sites. The agency’s director general, Rafael Grossi, maintains that inspections will be carried out and that verification is inseparable from any agreement. On the other side, Iran’s deputy foreign minister Kazem Gharibabadi says access to the struck facilities depends solely on a final deal with the United States, not on earlier commitments or outside pressure.

What is Tehran really asking in return?

Tehran’s calculation is laid out plainly. It is conditioning the opening of doors to inspectors on what its officials call the practical lifting of all sanctions by the other side. In other words, access to the nuclear sites is not a technical matter settled in a laboratory, but a lever in a political bargain. Until the sanctions regime is dismantled, Tehran treats inspections as a concession granted only at the end, not as a goodwill step at the start.

The situation on the ground confirms how stuck the process is. IAEA inspectors are still denied access to the sites that were bombed, which is precisely what the agency cares about most, because without a view into those facilities there is no reliable assessment of what nuclear material remains and in what condition. The only concrete movement is the inspectors’ recent visit to the Bushehr plant, a civilian nuclear power station in the south of the country, showing that the channel of communication is not entirely severed but remains far from full verification.

Grossi has framed his position carefully. He does not claim that inspections are a matter of days, nor that timing is decisive, but he insists on the principle that they must happen if the agreement is to carry any value at all. Without independent checks, any document signed between Washington and Tehran remains a promise with no control mechanism, and the Middle East has seen far too many such promises.

Why is Switzerland back on the agenda?

Diplomacy is now returning to neutral ground. Technical talks between the two sides are scheduled for June 29 and 30 in Switzerland, a country that has for decades served as an intermediary in the most sensitive files, including those in which Washington and Tehran have no direct diplomatic channel. The very fact that the talks are continuing, and at the technical level where political principles are translated into concrete steps, suggests that neither side is yet ready to declare failure.

For European chancelleries, which spent years investing in the survival of the nuclear deal and which view the sanctions regime as an instrument with an expiry date, the outcome of these talks carries weight that extends beyond Iran itself. Stability in the Middle East is part of the same geopolitical reality that shapes Europe’s energy security and Serbia’s position as a country that watches that balance from the sidelines yet feels it in its budget.

The talks in Switzerland will show whether the truce is a genuine start to a solution or merely a pause before another round of brinkmanship. Can Iran’s nuclear file be closed at all without independent oversight, or will verification once again remain trapped between politics and mistrust?
