"The Russian economy is collapsing," Habeck told lawmakers, adding that Germany had played its part here by reducing exports to Russia in March by 60%, with an even sharper fall expected in April.
Across the allied countries participating in the sanctions, exports to Russia fell by 53% over previous months, while the drop among neutral or pro-Russian states was 45%, according to the minister.
"Putin is still getting money but ... time is not working for Russia, it is working against Russia," he said.
As a result of the sanctions, Moscow had lost access to parts crucial to its ability to fight the war, Habeck said, such as "security updates for airplanes, with the result that the planes will soon be grounded".
