Wrth weithredu'r newidiadau hyn, rydym wedi ymrwymo o hyd i weithio gyda'r cwmni a'r undebau llafur i sicrhau dyfodol hirdymor i gynhyrchu dur yng Nghymru.
During the implementation of these changes, we remain committed to working with the company and the trade unions to secure a long-term future for steel making in Wales.
