BOC HK UnionPay Diamond Card

For frequent travellers to Mainland China, the BOC HK UnionPay Diamond Card earns double UnionPay bonus points on CNY transactions and provides comprehensive lounge access at 500+ mainland airports — a network no Visa or Mastercard lounge product can match in China. The card charges zero FX conversion fee on CNY transactions and provides CNY cash advances at preferential rates. For HK-Mainland commuters who split their year between HK and GBA cities, this is the most practical companion card to a Visa/MC miles card.
