China has officially put online lottery sales in the deep freeze, at least for the foreseeable future, following changes to lottery rules.

On Monday, China’s Ministry of Finance issued updated rules on lottery operations that redefine the term “illegal lottery” to include “welfare lottery tickets and sports lottery tickets sold by the Internet without authorization.” The changes will officially take effect on October 1.

The document, titled Amendments to the Regulations on the Administration of Lottery Regulations, follows a joint communiqué issued last month by 12 Chinese ministries and commissions “resolutely prohibiting the unauthorized use of the Internet to sell lottery tickets.”

Online lottery sales were suspended on a ‘temporary’ basis in March 2015 after a national audit uncovered rampant corruption at provincial lottery administration centers, including the failure to report all online sales to Beijing.
