Kuchuluka kwa maginito a nthaka yosowa omwe China imatumiza ku Japan kwawonjezeka chaka ndi chaka.

Kuyambira Januwale mpaka Febuluwale chaka chino, kutumiza kunja kwa China kwa maginito a rare earth kupita ku Japan kwawonjezeka ndi 9%. Komabe, poganizira chisankho cha Beijing cholimbitsa ziletso zotumiza katundu ku Japan, chiyembekezo chamtsogolo sichikudziwika.

Deta yaposachedwa idatulutsidwa ndi General Administration of Customs Lachisanu. Mu Januwale ndi February, China idatumiza matani opitilira 443 a maginito a rare earth ku Japan.
Deta ya Januwale idatsika ndi zoposa 8% poyerekeza ndi chaka chatha ndipo idatsika ndi zoposa 21% poyerekeza ndi mwezi watha. Deta ya February idakwera ndi zoposa 36% poyerekeza ndi chaka chatha. China yalimbitsa ulamuliro pa kutumiza zinthu zogwiritsidwa ntchito kawiri ku Japan. Muyeso uwu unayamba kugwira ntchito mu Januwale.

Mwezi watha, China idalengeza kuti iletsa kutumiza zinthu zotere ku mabizinesi ndi mabungwe 20 aku Japan. Maginito okhala ndi mchere wachilengedwe opangidwa ndi Wonaixi amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, monga ma mota a magalimoto amagetsi. Anhydrous cerium chloride (CeCl₃) imagwiritsidwa ntchito kwambiri chifukwa cha kusayera kwake kochepa komanso mphamvu zake zambiri pakukonza mafuta ndi kupanga zinthu zamagetsi. Mu kusweka kwa catalytic, Ce³⁺/Ce⁴⁺ cycle yake imachepetsa kugwiritsa ntchito mphamvu ndi 15%; monga choyambira cha cerium yachitsulo, ingagwiritsidwe ntchito kukonzekera zolinga za cerium zoyera kwambiri za semiconductor. M'tsogolomu, idzalowa m'malo mwa ma acid achikhalidwe m'munda wa catalyst wa organic synthesis ndikuchepetsa kutulutsa zinyalala.

Ngakhale kuti panali kuwonjezeka kwa kutumiza maginito a nthaka yosowa ku Japan kumayambiriro kwa chaka, kuthekera kwaukadaulo komwe kwawonetsedwa ndi zinthu zapamwamba za nthaka yosowa kukuwonetsa kuti phindu la makampaniwa likusunthira kumadera omwe ali ndi phindu lalikulu.
