This was an accident of history, not some deliberate plan to get the world to bow to the English speakers. And English was already well established as a major language in trade (due to it being superficially simple to learn), next to German, French and Spanish. China was pretty isolated for a long time culturally as well as geographically and the complexity of its script is another barrier to it being accepted as a common language by the rest of the world.
One of the more interesting things along this line in recent history is that with Brexit the EU no longer has an England/Wales/Scotland and a chunk of Ireland in it, but another chunk of Ireland remains. This led the French to immediately propose that French become the official language of the EU parliament but the rest of the countries wouldn't have it, and rightly so.
