Cov tuam txhab lag luam no tau tsim cov phiaj xwm kev tsim kho kom ruaj khov, uas lub hom phiaj siv qee yam ntawm PCR cov khoom siv rov ua dua tshiab rau lawv tus kheej cov khoom lag luam hauv ib lub sijhawm, txo kev siv cov ntaub ntawv tshiab, feem ntau suav nrog cov khoom siv yas, tshwj xeeb tshaj yog cov ntim tau yooj yim.Qee lub tuam txhab txawm teeb tsa lub tuam txhab xyoo 2030 los siv 100% cov khoom siv rov ua dua tshiab lossis rov ua dua tshiab rau txhua yam khoom yas.(Qhov no txhais tau hais tias kuv lub tuam txhab tau siv 10000 tons ntawm cov khoom tshiab hauv ib xyoos los ua cov khoom, tab sis tam sim no tag nrho lawv yog PCR (cov khoom siv rov ua dua tshiab).
