My main point was that Asia wasn't a vibrant cultural region which shared ideas extensively.

Those doesn't require more advanced architectural skills than just knowing how to pile bricks, Greece and Egypt built similar things long before the Romans. Roman architecture allowed them to build impressive stuff with far less effort which is why they were able to build hundreds of aqueducts.
Also most of the Great wall of china was built more than a thousand years after Rome's prime, so it doesn't count. The ancient parts of the wall wasn't much more than a very long rock fence, not really comparable to roman aqueducts.

So building aqueducts is impressive than building a complex functional megapolis, in the bronze age, with top-notch sewer system, with millions of people? Not sure what to make of this claim. I would still love to see evidence of the 'impressive stuff' that Romans built that was way ahead of all of the world civilizations.
