SAN FRANCISCO, June 1 (Xinhua) -- The U.S. state of California will ban travels it funds to Oklahoma from June 22, according to a California attorney general Friday.

"Oklahoma will be added to the list of restricted states for state-funded travel based on the discriminatory law that would allow private adoption agencies to refuse services to LGBTQ parents & foster children based on religious/moral grounds," Attorney General Xavier Becerra said in his tweet.

The move will make Oklahoma the 9th state on California's travel blacklist. A law in Oklahoma, which will take effect beginning in November, allows private adoption agencies to deny same-sex couples placement services and refuse to place LGBTQ foster children in homes.

Under a law adopted last year, California has banned state-sponsored travels by employees to the states of Alabama, Kansas, Kentucky, Mississippi, North Carolina, South Dakota, Tennessee, and Texas, which it said have passed laws that allow discrimination based on sexual or gender orientation.

"California taxpayers are taking a stand against bigotry and in support of those who would be harmed by this prejudiced policy," Becerra said.

"California will not use state resources to support states that pass discriminatory laws," the San Francisco Chronicle newspaper quoted Becerra as saying.
