You are trying to milk something that isn't there. Pork is considered dirty, so Muslim don't eat it. That doesn't mean they will put non-Muslims in jail for 7 years for eating pork.
hindus consider cows sacred, so you are actually offended and angry when Vietnamese slurp down their delicious national dish -- pho.
Vietnamese love to eat / slaughter cows so much they protest China using a picture of cutting a cow's tongue! When Vietnamese see a cow, they want to slaughter it or cut its tongue off. Cow's tongue is a delicacy. Now that must be very hard to stomach for Vietnam's new "friend."
You want to ally with somebody who hates your pho and wants to put you in jail for 7 years?
