Confucianism is a system of thought and behavior originated in ancient China. It was created by Chinese philosopher Confucius who considered himself a retransmitter of theology and values from the Shang and Zhou dynasties.
As you can see from above Confucianism originated in China so the statement saying that it was brought by missionaries from India is false.
