Izintengo ze-tungsten zase-China zihlale zizinzile evikini eliphele ngoLwesihlanu zingama-3 kuJanuwari, 2020 ezithintwe yiholide likaNcibijane kanye nesidingo esisivivi emakethe. Izintuthwane eziningi ezibambe iqhaza ezimakethe zinaka ukuqaliswa kwezinqubomgomo ezahlukahlukene kanye nokukhululwa komjikelezo omusha wezibikezelo zentengo ye-tungsten ezinkampanini ezisohlwini lwe-tungsten.

Emakethe yokugxilisa ingqondo ye-tungsten, abathengisi babenethemba lokwesekwa kwenqubomgomo kanye nokudla ngemva kweholide, okuhambisana nokwehla kokukhiqizwa kwezinkampani phakathi nenkathi yoMkhosi Wasentwasahlobo, imakethe yayinomqondo ophakeme oqinile, kodwa amadili amanani aphezulu ayengakaphothulwa. Imakethe ye-APT yasekelwa izindleko zempahla eluhlaza. Izimboni ezincibilikisayo zahlala zinezinga eliphansi lokusebenza njengoba zibhekene nengcindezi evela ohlangothini lwesidingo. Ngokuqondene nemakethe yempuphu ye-tungsten, iphinde yazinza ngokuhambisana nayo yonke inkambiso yemakethe.
