Swedish Foreign Minister Maria Malmer Stenergard also called for sanctions on Russian fertilizers and a halt to the export of luxury goods to the country, in comments at an annual security conference in the Swedish town of Salen.
"The pressure on Russia must increase. Therefore, my Finnish colleague Elina (Valtonen) and I have presented three proposals for the upcoming sanctions package," she said, referring to the Finnish foreign minister.
"We want to see a total ban on all European companies offering any services whatsoever to ships carrying Russian oil, gas, and coal.
"No transport. No transfers of cargo between ships. No insurance. No repairs in port."
The EU is currently preparing its 20th sanctions package aimed at punishing Russia for its war in Ukraine. Previous sanctions have focused heavily on Moscow's oil and gas sector, the Kremlin's primary source of income.
The EU also imposed tariffs on fertilizer imports from Russia in July last year. Russia produces more than 20 percent of the world's fertilizer and accounts for around a quarter of the EU's fertilizer imports.
Stenergard also urged the 27-nation bloc to stop exporting its luxury goods to Russia, calling it "not crucial for the Russian war economy" but arguing it was "morally right."
"It provokes me that wealthy Russian consumers can dress in expensive Italian designer clothes and drink fine French wines," Stenergard said.
"A country should not be able to violate European values and still be able to take advantage of exclusive European products."
The EU has imposed 19 packages of sanctions against Russia since its invasion of Ukraine in 2022 and is currently in the process of agreeing on a 20th round.
In total, more than 2,600 individuals and companies are now sanctioned
"The experience from the war in Ukraine clearly shows how crucial a robust and sustainable air defense is," Swedish Defense Minister Pal Jonson said.
"By building up territorial air defense units, we complement the existing air defense and strengthen the protection of mobilization and combat units. This raises the threshold against attack, strengthens Sweden's defense capability, and at the same time contributes to NATO's collective deterrence and defense."
"Previously, the air defense's primary task has been to protect its own military units and military infrastructure," the Swedish government said in a statement announcing the investment.
"Now the government is moving forward with building a territorial air defense capability that will strengthen the protection of combat units, including the mobilization of military defense with the possibility of protecting cities and civilian infrastructure."
The government said the new territorial air defense will be short-range, consist of a number of independent company-sized units, and utilize simple systems that are flexible, allowing different types of weapons, radar, and technical systems to be combined.
This will "create the opportunity to protect, among other things, civilian objects such as bridges, railway junctions, critical infrastructure such as nuclear and hydroelectric power plants and cities," the government said.
Sweden is one of the newest members of the NATO alliance, joining in 2024 after first applying in 2022, just months after Russia launched its full-scale invasion of Ukraine.
It has been a member of the EU since 1995.
