I have a NZ APEC card and SIN was the last country to sign off mine.
In using it it is great, but still prefer to get a visa to China than having to try to add an extra 20mins on average checking into non Shanghai or Beijing hotels whom have zero knowledge of them and takes longer trying to convince them that the APEC card is ones Visa. Having a visa also is just easier, quicker, faster when checking into a hotel.
Currently I am relying on my APEC card, cause my passport expires in April next year and last Visa expired in May gone and need 18 months on passport to get new 12 month multi visa.
OT, but I am in debate if I will travel past October, cause will need 6 months on passport to do so which I will not have come November unless I get new, but NZ passports go back to 10 Year from current 5 Year ones on 1st January next year.
