These strips and wallplates originate from China. I've seen the wallplates in Chinese hotels. Also saw one at Kuala Lumpur International airport, Malaysia. The 4 way strips are on sale everywhere in Macau, and they can be found in markets in Malaysia. I've even seen them in £1 shops in the UK.
They can't cope with BS546 15A plugs, but almost anything else will fit including Australian, Italian, and Swiss plugs. Although these is a hole for the earth on Italian and Swiss plugs these are no contacts behind the hole.
