For the purposes of this section, the yearly tally of orbital launches by country assigns each flight to the country of origin of the rocket, not to the launch services provider or the spaceport. For example, Soyuz launches by Arianespace in Kourou are counted under Russia because Soyuz-2 is a Russian rocket.
