Mae cysylltiad Cymru â Chongqing (Rhanbarth Dinesig o ryw 33 miliwn o bobl ac un o’r rhannau o Tsieina sy’n datblygu gyflymaf) wedi bod yn ffynnu ers llofnodi’r Memorandwm Cyd-ddealltwriaeth cyntaf yn 2006. Y cysylltiad hwn yw’r ehangaf a’r prysuraf rhwng unrhyw ran o’r DU a Tsieina.
Wales' relationship with Chongqing (a Municipality of some 33 million people and amongst the fastest developing parts of China) has been thriving since the signing of the first MOU in 2006.  The relationship is the most extensive and most active between any part of the UK and China.
