Before I retired I had many trips to Chinese banks to help them migrate to the next level of MQ. At the time I would say that some of them were leading edge, for example a sysplex in Beijing, and a sysplex in SHanghai, with replication both ways, so the DB2 databases were kept in sync within a couple of seconds - a world first. One bank had more personal current accounts than there are people living in America (over 300 million) The banks usually worked together informally, so good practice was shared between them.
