Noma iyiphi izimpahla ezithunyelwa ngaphandle ngokungcebeleka China amandla abathumeli bama-transformer bahambisana ngokuphelele nekhwalithi yezimpahla ezithengiswa e-China, futhi bahlolwa okuqinile. Abathumeli besiteshi esincane saseShayina benza kahle imikhiqizo yabo ngaphambi kokuthumela ngaphandle, okungathuthukisa ukusebenza kokuphepha kwemikhiqizo futhi kuvimbele ngempumelelo ukuqhuma kwama-transformer kagesi. Abahlinzeki be-transformer benethiwekhi abacwiliswa ngokwezifiso bawoyela babambisana nezimboni eziningi zaseShayina ukuze ngokuhlanganyela bakhe ama-transformer ekhwalithi ephezulu azothunyelwa ngaphandle.
