Winston Peters appears to have had a snide swipe at Donald Trump over his tweet blaming Russia for the chemical attack in Syria.

President Trump's tweet said President Putin, Russia and Iran are responsible for backing 'Animal Assad', adding there'll be a big price to pay.

Our Foreign Minister wouldn't be drawn into commenting on the tweet saying he wasn't doing our foreign policy on twitter.

"We somewhat elevate NZ foreign affairs in ministerial positions, that's why we're a great democracy."

Asked if he believes Donald Trump denigrates foreign affairs, Peters laughed and told reporters: "You take a wild guess at what I'm saying, okay."
