This is expected though, right? Even in Europe, unless you're a verysmall country, most business you deal with is domestic. Do by default, the largest companies mare going to be in the largest economies. Doesn't mean you can't get lucky every now and again, but you are handicapped by not having a large domestic consumption base protected via political independence.

China and the US are continent-scale megastates. Obviously a mid-sized Atlantic island like the UK, or smallish peninsula like Italy, are not going to compete on scale.
