Cause it is too effing hard. The grammar is easy but remembering thousands of characters is a major headache for any linguist.
True but there are others who have learnt it and they are not Chinese origin so whats stopping PAkistanis:
Here is a list of some
William Hootkins: American actor
Herbert Hoover: American President
Kenneth Scott Latourette: American academic historian
Paul Robeson: American singer, actor and activist[
Princess Maha Chakri Sirindhorn: Thai princess
Gary Snyder: American poet and essayist. Winner of the Pulitzer Prize for Poetry.
Mira Sorvino: American actress
Bob Woodruff: American television journalist, ABC News
I havent seen one Pakistani learning it - no offense to them, just something to point out- but please prove me wrong otherwise.
Futher to this, learning and understanding Chinese and Pakistani culture and language can only bring China and Pakistan even closer.
