Xu Niansha adalengeza kuti zaka khumi zapitazi, makampani opanga makina ku China adalimbikira kuchita malonda akunja ndi mgwirizano kuti alimbikitse kutsegulidwa kwapamwamba kumayiko akunja.Zogulitsa zamakina zatumizidwa kumayiko ndi zigawo zopitilira 100.Zogulitsa zopangidwa ku China ndi zida zaku China zimakhala ndi mbiri yapadziko lonse lapansi ndikufalikira padziko lonse lapansi.

Kutumiza ndi kutumiza kunja kwa makina opangira makina kunapanga 17.16 peresenti ya malonda akunja a China mu 2021, kuchokera pa 16,74 peresenti mu 2012. Pakati pawo, gawo lazogulitsa kunja linakwera kuchokera ku 17,11% kufika ku 20,11%;Kuchuluka kwa malonda kudakwera mpaka 46.48% kuchokera 23.36%.Izi zikuwonetsa bwino kuti makina aku China amatenga gawo lofunikira kwambiri pamakampani opanga zinthu padziko lonse lapansi.

Kuonjezera apo, ndondomeko ya malonda a kunja yakhala ikukonzedwa mosalekeza.M'zaka 10 zapitazi, kapangidwe kazinthu zogulitsa kunja kwamakampani amakina aku China akhala akukonzedwa mosalekeza.Ikutukuka kwambiri kuchokera pakukonza malonda ndi zinthu zapakati ndi zotsika kupita ku malonda wamba ndi zinthu zomwe zili ndiukadaulo wapamwamba komanso mtengo wowonjezera komanso zida zonse.M'zaka zaposachedwa, malonda ogulitsa makina amagulitsa pafupifupi 70%.Zigawo zamagalimoto, mwayi wanthawi zonse wa zida zamagetsi zamagetsi ndi makina ena ogulitsa kunja kwachulukirachulukira m'zaka zaposachedwa, magalimoto, makina opanga uinjiniya, zida zamakina monga momwe zimagwirira ntchito kunja ndizabwino kwambiri, galimotoyo imatumiza kunja magalimoto opitilira 2 miliyoni mu 2021, zofukula zamakina, zonyamula katundu, ma bulldozers, kukula kwamphamvu kwa forklift yamagetsi, kumakhala mphamvu yayikulu yotumiza kunja kwatsopano.
