SHANGHAI — Google has accused the Chinese government of disrupting Gmail in the country, making it difficult in the last few weeks for users here to gain access to the company’s popular e-mail service.

Google said that it was not having any technical problems with Google’s main Web site or Gmail service in China.

“There is no issue on our side; we have checked extensively,” Google said in a statement released Sunday. “This is a government blockage, carefully designed to look like the problem is with Gmail.”

Analysts who track Web developments say that the Chinese government may be intentionally disrupting access to Google and other Web services as part of a campaign to tighten Internet controls and censor material.
