Ngomhlaka-14 Disemba, uNgqongqoshe Wezimboni waseNingizimu Korea kanye noNgqongqoshe Wezimboni, Amandla kanye Nokukhishwa Kwekhabhoni wase-Australia basayine isivumelwano sokubambisana eSydney. Ngokwesivumelwano, ngo-2022, iNingizimu Korea kanye ne-Australia zizosebenzisana ekuthuthukiseni amanethiwekhi okuhlinzeka nge-hydrogen, ubuchwepheshe bokubamba nokugcina ikhabhoni, kanye nocwaningo kanye nentuthuko yensimbi ekhipha ikhabhoni ephansi.
Ngokwesivumelwano, uhulumeni wase-Australia uzotshala amaRandi ase-Australia ayizigidi ezingama-50 (cishe amaRandi ayizigidi ezingama-US$35) eNingizimu Korea eminyakeni eyi-10 ezayo ukuze kwenziwe ucwaningo kanye nokuthuthukiswa kobuchwepheshe obusebenzisa i-carbon ephansi; uhulumeni waseNingizimu Korea uzotshala amaRandi ayizigidi eziyizinkulungwane ezintathu (cishe amaRandi ayizigidi ezingama-US$2.528) eminyakeni emithathu ezayo. Isetshenziswe ukwakha inethiwekhi yokuphakelwa kwe-hydrogen.
Kubikwa ukuthi iNingizimu Korea ne-Australia bavumile ukubamba umhlangano wokushintshana ngobuchwepheshe obusebenzisa ikhabhoni ephansi ngo-2022, nokukhuthaza ukubambisana phakathi kwamabhizinisi ala mazwe womabili ngetafula lezingxoxo zebhizinisi.
Ngaphezu kwalokho, uNgqongqoshe Wezimboni waseNingizimu Korea ugcizelele ukubaluleka kocwaningo lokubambisana kanye nokuthuthukiswa kobuchwepheshe obusebenzisa ikhabhoni ephansi emcimbini wokusayina, okuzosiza ukusheshisa ukungathathi hlangothi kwezwe kwekhabhoni.
