"It's clear from conversations we have had with Chinese government officials that they find the redirect unacceptable - and that if we continue redirecting users, our Internet Content Provider licence will not be renewed.
"Over the next few days we'll end the redirect entirely, taking all our Chinese users to our new landing page," he said, explaining that the new page on Google.cn would have a link to the Hong Kong site.
Drummond said that Google had resubmitted its application for renewal of the license to reflect the company's "new approach".
But analysts said that the move was unlikely to end the spat between Chinese authorities and the search giant, which says it has been subjected to cyber-attacks and censorship in the country.
Duncan Clark, the chairman of technology consultancy BDA China, said the Chinese government would likely use the licence renewal as an opportunity to show their displeasure at the redirect, which it has been powerless to prevent.
"Clearly aggrieved, the authorities have attempted now to show their power," he said.
Following Google's blog announcement, Chinese foreign ministry spokesman Qin Gang told reporters: "A foreign internet company operating in China should abide by Chinese laws and regulations."
Beijing has denied any role in the cyberattacks which Google has said targeted the Gmail accounts of Chinese dissidents.
Chinese authorities said it was "totally wrong" for Google to stop filtering its Chinese-language search engine.
