Donald Trump is giving himself license to take over other planets, according to the Russian space agency.

Roscosmos accused the president of creating a basis to seize other worlds with a new executive order about commercial mining in space.

The new rules damage the scope for international co-operation in space after they were made official this week, the space agency said.

It said the United States would seek to negotiate "joint statements and bilateral and multilateral arrangements with foreign states regarding safe and sustainable operations for the public and private recovery and use of space resources".

It said US citizens should have the right to engage in such activity and that "outer space is a legally and physically unique domain of human activity, and the United States does not view it as a global commons".

Roscosmos said the order put the United States at odds with the notion of space belonging to all humanity.

"Attempts to expropriate outer space and aggressive plans to actually seize territories of other planets hardly set the countries (on course for) fruitful cooperation," its statement said.

Relations between Russia and the United States are at post-Cold War lows, but cooperation on space has continued despite an array of differences over everything from Ukraine to accusations of election meddling.

Kremlin spokesman Dmitry Peskov told reporters that "any kind of attempt to privatise space in one form or another - and I find it difficult to say now whether this can be seen as an attempt to privatise space - would be unacceptable".
