Palestinian leader Mahmoud Abbas wrapped up a trip to China Friday after seeking economic aid and voicing support for Beijing’s repressive policies toward Muslim minorities in the northwestern region of Xinjiang.

During his four-day visit, Abbas met with Chinese President and head of the ruling Communist Party Xi Jinping. The leaders then issued a joint statement endorsing Beijing’s domestic and foreign policies and repudiating Western concepts of human rights.

In the statement, the Palestinian Authority said issues regarding China’s policy toward Muslims in Xinjiang have “nothing to do with human rights and are aimed at excising extremism and opposing terrorism and separatism.”

“Palestine resolutely opposes using the Xinjiang problem as a way of interfering in China’s internal affairs,” the joint statement said.
