Beijing dominates the global supply of gallium nitride – which has been revealed as a key component in its Ludi Tance-4 01 satellite

It orbits 36,000km (22,000 miles) above the Earth and is able to stay in what is known as a geosynchronous orbit, which keeps it fixed over the same spot.
This allows it to monitor both large areas of the planet and moving targets – something the United States has spent decades trying to achieve without success.
