In building his empire did Alexander the great conquer Persia India and China?

Alexander the great conquered Persia and extended his empire into parts of India, notably defeating King Porus at the Battle of the Hydaspes in 326 BCE. However, he did not conquer China; his campaigns did not reach that region. After reaching the Indian subcontinent, his troops eventually refused to march further east, leading to his return to Babylon. Thus, while he achieved significant conquests, China remained outside his empire.
