Tiantai Buddhism's international exchange has done focusing on China and Japan.

We were interested in exchange with Japanese Tiantai Buddhism as Supreme Patriarch Sangwol Wongak instructed us to grasp the fact of Japanese Tiantai Buddhism after the diplomatic relation between Korea and Japane was normalized in 1964. It was promoted in earnest as 「the Fact of Korean Tiantai Buddhism」 was introduced to Japan in Issue 19 of Japanese 『Tiantai Studies Newspaper』 after Dr. Sekiguchi Shindai (關口眞大) visited Guinsa Temple on September 1976.

We agreed that Korean and Japanese executives would carry out exchange in Seoul on July 1978 and the agreement was concluded naming it 「Korea and Japanese Tiantai Friendship Exchange Meeting」 on July 1979. In the agreement, the intent said, "Tiantai Buddhists in the both countries promote friendship exchange and make a contribution to the prosperity of Tiantai Buddhism of the both countries and world peace through close partnership and links based on Buddha's spirit of peace (和) and the ideology of Tiantai Buddhism that Priest Zhiyi founded". We have carried out exchange and promoted friendship almost every year and led cultural exchange between the both countries.

Korean executives of Tiantai Buddhism attended the inauguration ceremony of the quarters of a head monk in Gukcheongsa, China. And the persons in the Chinese Buddhist circle visited Guinsa Temple and interacted with one another. So exchange of Tiantai Buddhism among the three countries of Korea, China, and Japan was begun. And then, this exchange was shown by holding the great religious ceremony to commemorate Priest Zhiyi by the three countries as we marked his 1,400th year of nirvana.

The opportunity was the agreement to hold the joint great religious ceremony to commemorate Priest Zhiyi by the three countries of Korea, China, and Japan as we marked his 1,400th year of nirvana when the executives of Japanese Tiantai Buddhism visited Guinsa Temple on April 1996. The international status of Chontae Order of Korean Buddhism has risen as it has played a great role in exchange of Tiantai Buddhism among the three countries.

Now, international exchange of Tiantai Buddhism has actively done focusing on symposiums. Scholars from the West and Asia as well as China and Japan have been invited to the international symposiums that have been held by the Cheontae Buddhist Culture Research Center once per year. And they have carried out academic exchange in them. In the international symposiums that began from 1998, 20 Chinese scholars, 14 Japanese scholars, 3 American scholars, 2 Norwegian scholars, 2 scholars from Myanmar, a Australian, a Frenchman, a German, a mongolian, and a Sri Lankan as well as Wulimin (吳立民) from China in the 1st symposium and Muranaka Wusho (村中祏生) from Japan have made presentations in them.
