​From behind a red strip of tape to ensure coronavirus-related social distancing, placed on a handmade Persian carpet in Iran’s presidential palace, Switzerland’s Foreign Minister Ignazio Cassis greeted President Hassan Rouhani for a meeting that marked 100 years of diplomatic ties between the two nations.

“The path is open for America to return to the JCPOA,” Rouhani said, in reference to the Joint Comprehensive Plan of Action, widely known as the Iran nuclear deal, which US President Donald Trump shredded in 2018. “We expect the friendly and free countries of the world not to resort to silence,” the Iranian president added, as he once again criticized the US economic pressure, which officials in Tehran have repeatedly lamented as “terrorism” or “economic warfare."

The immense pressure, Iran complains, is targeting its civilian population and their livelihoods. And to bypass it, the Islamic Republic has been exhausting multiple solutions, one of which is the “Swiss humanitarian channel,” officially launched in January with the aim of facilitating Iranian payments for the imports of much-needed medicines and food into the sanctions-hit country.

Rouhani called for a boost in the channel’s activity by the Swiss government, which protects Iranian and American interests on the soils of the two countries in the absence of formal diplomatic relations between the two archenemies. In a veiled mention of the same transaction corridor, Iran’s Foreign Minister Mohammad Javad Zarif also expressed gratitude for Switzerland’s efforts “to mitigate US sabotage.”
