unless i'm misremembering gdp calculations the trade portion of gdp is a simple exports - imports = total trade value added to gdp. china's surplus is up 200bil over 2023. that means that fully half of china's gdp growth was due to increased exports (imports were up about 1% vs exports being up 6%) it doesn't seem terribly sustainable. for comparison the us runs a trade deficit of 700billion~
