Bizarre question - can the US ICBC issued Union Pay card be used in Cuba?

Apparently Union Pay cards CAN be used in Cuba (ihttps://www.unionpayintl.com/en/mediaCenter/newsCenter/companyNews/3009113.shtml). Visa, Master, and Amex are all US based companies, so their worldwide affiliates are prohibited from operating in countries with US financial embargoes, but since Union Pay is China based it (apparently) doesn't have the same restrictions. However, I'm guessing the US issued one would disqualify itself by being US issued.

Has anyone been able to use this card in Cuba?

(Slightly related side note, I visited Myanmar in 2005 while the US sanctions were still going on, and Visa/MC/Amex couldn't be used at all. I was able to use my Japan-issued JCB card at a couple of hotels though, since JCB was Japan based and therefore not part of the embargo. That's why I'm wondering about Cuba & Union Pay.)
