Yn flaenorol mae Llywodraeth Cymru wedi defnyddio cyllid yr UE i helpu i fynd i'r afael â diweithdra, cyflwyno prentisiaethau a hyfforddiant, creu a thyfu busnesau, a buddsoddi mewn seilwaith a phrosiectau mawr fel Metro De Cymru a'r sector ynni adnewyddadwy yng Ngogledd a Gorllewin Cymru.
The Welsh Government previously used EU funding to help tackle unemployment, deliver apprenticeships and training, create and grow businesses, and invest in infrastructure and major projects like the South Wales Metro and the renewable energy sector in north and west Wales.
