I have to be honest I can't be 100% as I don't physically have one of the clone sets to compare them. But based on the photos the connectors are identical, the markings on the side of the track pieces (the brickwork) is identical and the design of the tracks themselves are identical. Bearing in mind the cars are also 3 car sets with a middle power car, with 4 axles on each car and the switch on the power car in the same place as the Daiso ones I would say there is a 99.9% chance they are both made by the same factory to the same design. Do we know anyone who has actually bought one of the clones? If so if they want to measure the width of the track I can do the same to confirm this
Happily collecting things all my life...
