NEW YORK/PALO ALTO, U.S. -- When Clare Liu heard about U.S. President Donald Trump's decision to ban the popular Chinese messaging app WeChat, she immediately thought of her parents.
"WeChat is the main app that I use to chat with my parents in China, now I have to think about an alternative way to contact them," said Liu, 26, a finance professional living in New York, adding that she has tried Skype but it's not as convenient.
