Zen or (ch'an) buddhism evolved in China, and was very influenced by Taoism. In fact, Quanzhen (Complete Reality), a sect of Taoism, is very influenced by Buddhism, and even incorporates some Buddhist sutras into their scriptures. Both advocate meditation as the key component of practice in order to gain enlightenment/immortality (at least to the best of my knowledge)

Knowing others is wisdom, Knowing the self is enlightenment- Lao Tzu
