Chinese standards & workmanship, are you surprised!
CREC & CRCG did a few projects in Papua New Guinea when I lived there, same level of workmanship, 1 of their high rise projects got condemned for substandard materials and failing to install as per stipulated materials! It the same all over the Pacific where they win contracts on price and brown envelopes, cut corners like this latest debacle in Bangkok, so nothing has changed, I guess they fit in quite well in Thailand!!!
