The current account balance (BoP) considers goods and services. And it's not bilateral relationships that matter, but the aggregate global imbalance. To say that America is the engine of the deficits that absorbs the world's surpluses is trivially accepted by economists.

There's a nice table to understand how skewed things are really with the balance of payments here. America's deficit is 10x higher than the second rank with the UK, which should illustrate how difficult it is for the surplus countries to find alternatives. In any case, this whole situation on excessively relying on one country to buy all the world's exports is a stupidly unstable situation.
