Story highlights Putin said that the use of sanctions were 'doomed to fail'

He supports the climate change pact that Trump wants to pull the US from

(CNN) Russian President Vladimir Putin has taken a thinly-veiled stab at US President Donald Trump's policy agenda, slamming US sanctions and trade protectionism just a day before the leaders' highly-anticipated meeting in Germany.

The two men are scheduled to officially meet for the first time on Friday in Hamburg on the sidelines of the G20 summit.

German newspaper Handelsblatt published an article Thursday penned by Putin, who sang the G20's praises while criticizing the use of sanctions and protectionist trade policies, both measures associated with the US administration.

"Protectionism is becoming the norm, while unilateral, politically motivated restrictions on trade and investment, as well as technology transfer, are nothing but masked protectionism," Putin wrote.

"We believe that these sanctions are not only doomed to fail, but also run counter to the G20 principles of cooperation in the interests of all countries."
