ʻO nā kumukūʻai ferro tungsten a me tungsten pauka i ka mākeke Kina e hoʻololi nāwaliwali no ka nele o ka mākeke i ka wai i hoʻopilikia ʻia e ka hoʻomau ʻana o ka coronavirus a puni ka honua.Pono nā mana he nui e hoʻihoʻi hou i nā laka, e hōʻemi ana i nā kālepa mai nā mākeke o waho.
Aia ka mākeke concentrate tungsten ma muli o ka nāwaliwali mau i ka ʻaoʻao koi.ʻAʻole makemake nā ʻoihana mining e kūʻai aku ma nā kumukūʻai haʻahaʻa a ʻimi nā mea kūʻai aku i nā kumu kūʻai haʻahaʻa.Ma muli o kēlā, ʻaʻole i pau nā hana maoli.Noho haʻahaʻa nā hale hana hoʻoheheʻe e pale aku i nā pilikia a kūʻai aku ma muli o ke koi paʻa.Ke kali nei ka hapa nui o ka poʻe insiders i nā kumukūʻai alakaʻi hou mai nā hui tungsten.He nāwaliwali ka mākeke pauka tungsten akā kākoʻo ʻia e ke kumu kūʻai kiʻekiʻe.
