Police aren't watching the people in China either:

"It is forbidden for Communist Party cadres, civil officials (including those who have retired) and students to participate in Ramadan religious activities."
The statement, posted on the Xinjiang government website, urged party leaders to bring "gifts" of food to local village leaders to ensure that they were eating during Ramadan.

Nobody is forcing them to eat, people are just trying to get the local village leaders to eat.

Nobody is making your average Xiao Muslim eat.
