Sundar Pichai has told a conference in San Francisco that the ambition remains in its early stages and it may not, in fact, ever progress.
He explained: "We wanted to learn what it would look like if Google were in China, so that's what we built internally.
"It's very early, we don't know whether we would or could do this in China but we felt like it was important for us to explore. I think it's important for us given how important the market is and how many users there are."
Pichai explained that Google - which does not currently operate in China - would be able to serve "well over 99 percent of queries", based on the tests it's already conducted.
Earlier this month, meanwhile, Google appealed its $4.9 billion fine for allegedly using the Android operating system to "cement its dominance" in the search-engine market.
The firm was handed the fine back in July by the European Commission, which argued that Google had "denied rivals the chance to innovate and compete".
But Google has launched an appeal against the decision, though it could still take years to reach a resolution.
