Been a while since I've explored this same thing. I think the American imperial gauging is wider than the Asian metric form.
Yes, it is. It looks like you have a little room at the nut to widen the spacing...but as has been pointed out, be careful to not run them too close because the strings will be liable to shoot off the edge when you press down.
The proper way to fix the guitar at the bridge end is to get a US-sized bridge, take the old one off, dowel the holes, redrill the body for the new bridge (which will have different screw spacing)...done. This has the advantage that the string spacing will be correct before they get to the saddles, so tuning stability will be better.
The easy way to fix it is to just buy a set of US-sized
vintage* saddles and fit those to your existing bridge. It will be a bit of a squash to get them in there, but they will fit. The strings will need to spread out a bit from the trem block to the saddles, which is not ideal, but it will give you the spacing you want.
*it won't work with modern saddles, they are too bulky.
