The Boston Celtics’ Enes Kanter recently took another jab at Los Angeles Lakers star player LeBron James for reportedly choosing money over morals on the issues of forced labor in China, Uyghurs and Tibet.

What happened: Kanter, 29, took to social media on Thursday to again call out James, 36, for not standing up against Nike and its alleged use of forced labor when manufacturing its shoes.

“Did you educate yourself about the slave labor that made your shoes or is that not part of your research?” the NBA center asked James.

He included an emoji of the Chinese flag next to “Big Boss,” insinuating James and the NBA are tip-toeing around the Chinese government’s human rights abuses to maintain the multibillion-dollar relationship. The photos are of shoes displaying the same message artistically. The writing on the toes read “Principals > Money” and “Morals > Money.”

Kanter has remained outspoken regarding the human rights situation in China. He’s called for Nike to use its influence there and largely spoke in generalities until bringing James and Michael Jordan into the conversation last month.

He also posted pictures of four new sneakers featuring James. On one of the sneakers, the “Space Jam 2” star can be seen being crowned by China’s Xi Jinping. The other shoes’ messages read, “I Am Informed and Educated on the Situation” and “Hey, Still Researching and Getting Educated?”

Kanter has been speaking out against China on several political issues, including their treatment of Uyghurs, Tibet and Taiwan. Last week, Taiwanese President Tsai Ing-wen thanked the NBA star for supporting Taiwan’s freedom. He also called for the boycott of the 2022 Winter Olympics in Beijing while calling Xi an “insecure tyrant.”
