Ka la 2 Mmesa, 2025, Donald Trump o saenne ditaelo tse pedi tsa phethahatso tsa "tefiso e tshwanang" White House, a beha "tefiso e tlase ya motheo" ya 10% ho balekane ba kgwebo ba fetang 40 bao US e tsamaisanang le bona kgaello ya kgwebo. China e tobane le tefiso ya 34%, eo, ha e kopantswe le sekgahla se teng sa 20%, e tla ba 54%. Ka la 7 Mmesa, US e ile ya eketsa tsitsipano, ya sokela tefiso e eketsehileng ya 50% ho thepa ya China ho qala ka la 9 Mmesa. Ho kenyeletswa le ho nyoloha ha ditheko tse tharo tse fetileng, thepa e romellwang kantle ho naha ya China ho ya US e ka tobana le ditefiso tse hodimo ho 104%. Ha e arabela, China e tla beha tefiso ya 34% ho thepa e tswang US. See se tla ama indasteri ya dikhemikhale ya lehae jwang?
Ho ya ka tlhahisoleseding ya 2024 mabapi le dikhemikhale tse 20 tse ka sehloohong tsa China tse tswang US, dihlahiswa tsena di shebane haholo le propane, polyethylene, ethylene glycol, kgase ya tlhaho, oli e tala, mashala le di-catalyst—haholoholo ke thepa e tala, thepa e sebetswang ya mantlha, le di-catalyst tse sebediswang tlhahisong ya dikhemikhale. Har'a tsona, di-hydrocarbon tse tletseng acyclic le propane e metsi di etsa 98.7% le 59.3% ya thepa e tswang US, ka bongata bo fihlang ditoneng tse 553,000 le ditone tse dimilione tse 1.73, ka ho latellana. Boleng ba thepa e tswang US feela bo fihlile ho $11.11 bilione. Le hoja oli e tala, kgase ya tlhaho e metsi le mashala a coking le tsona di na le boleng bo hodimo ba thepa e tswang kantle, diabo tsa tsona kaofela di ka tlase ho 10%, e leng se etsang hore di nkelwe sebaka ho feta dihlahiswa tse ding tsa dikhemikhale. Litefiso tsa ho lefa di ka eketsa ditjeo tsa thepa e tswang kantle mme tsa fokotsa bongata ba thepa e kang propane, e leng se ka eketsang ditjeo tsa tlhahiso le ho tiisa phepelo ya di-derivatives tse tlase. Leha ho le jwalo, tshusumetso hodima oli e tala, kgase ya tlhaho le mashala a belang a tswang kantle ho naha e lebelletswe ho fokotseha.
Ka lehlakoreng la kantle ho naha, dikhemikhale tse 20 tse ka sehloohong tse romellwang kantle ho naha tsa China ho ya US ka 2024 di ne di laolwa ke dipolasetiki le dihlahiswa tse amanang le tsona, mafura a diminerale, oli ya diminerale le dihlahiswa tsa ditshila, dikhemikhale tsa tlhaho, dikhemikhale tse fapaneng, le dihlahiswa tsa rabara. Dipolasetiki feela di ne di ikarabella bakeng sa dintho tse 12 ho tse 20 tse ka sehloohong, mme thepa e romellwang kantle ho naha e le ya boleng ba $17.69 bilione. Bongata ba thepa e romellwang kantle ho naha ya dikhemikhale e yang US e etsa ka tlase ho 30% ya kakaretso ya Chaena, mme diatlana tsa polyvinyl chloride (PVC) di le hodimo ka 46.2%. Diphetoho tsa ditefiso di ka ama dipolasetiki, mafura a diminerale le dihlahiswa tsa rabara, moo Chaena e nang le karolo e hodimo ya thepa e romellwang kantle ho naha. Leha ho le jwalo, mesebetsi ya dikhamphani tsa China e kopaneng lefatsheng ka bophara e ka thusa ho fokotsa tse ding tsa ditshitiso tsa ditefiso.
Khahlanong le maemo a ntseng a eketseha a litefiso, ho feto-fetoha ha leano ho ka sitisa tlhoko le litheko tsa lik'hemik'hale tse itseng. 'Marakeng oa kantle ho naha oa Amerika, lihlopha tse kholo joalo ka lihlahisoa tsa polasetiki le lithaere li ka tobana le khatello e kholo. Bakeng sa thepa e tsoang US, thepa e tala e ngata joalo ka propane le li-hydrocarbon tse saturated acyclic, tse itšetlehileng haholo ka bafepedi ba Amerika, li ka bona litlamorao tse bonahalang botsitsong ba litheko le ts'ireletso ea phepelo bakeng sa lihlahisoa tsa lik'hemik'hale tse theohelang.
