Canada's waiving of sanctions on a crucial part of the Russian gas transportation system is angering the Ukrainian government.
Ukrainian President Volodymyr Zelenskyy said in his address on Monday that Canada's decision to send a turbine back to Germany was unacceptable.
Natural gas comes from Russia to Germany. Russia cut 40% of its natural gas supplies to Germany last month due to the Canadian government's sanctions against Russia.
Canada was asked to waive the sanctions and give back the turbine by Germany. According to the Canadian Broadcasting Company, Canada announced over the weekend that the turbine would be sent back to Germany.
Zelenskyy said in his Monday speech that if a terrorist state can squeeze out an exception to sanctions, what exceptions will it want?
The question is very dangerous for all countries of the democratic world.
He said that the exception to sanctions would be seen in Moscow as a sign of weakness.
A host country may summon a country's ambassador to show its displeasure.
Zelenskyy said there was no doubt that Russia would shut down its gas supplies to Europe.
Robert Habeck, Germany's economy minister, is worried that the internet service may not return after it closes for maintenance in July.
The US government supports Canada's decision to return the turbine, saying it will allow Germany and other European countries to replenish their gas reserves, increase their energy security and resilience, and counter Russia's efforts to weaponize energy, according to a report.
Canada is sending weapons to Ukraine to help fight Russia and Prime Minister Trudeau is going to meet Zelenskyy in May.
The Canadian government did not respond to the request for comment.
Germany, Europe's largest economy, is dependent on natural gas from Russia and plans to stop buying it by the year 2024. European countries are trying to reduce their dependence on Russian energy.
