Peter Tran Van Khoat aka Khoat Van Tran aka Khoat Tran aka Fr. Khoat Tran aka Dr. Khoat Tran is a most enigmativ person, upon whom the whole Siri claim stands or falls.

Non Dr. Khoat Tran is running or trying to build a hospital in Vietnam.

Fr. Khoat has given testimony to several people.
Mr. Gary Giuffre sent Fr. Khoat to see Cardinal Siri in the Spring of 1988. 
This webmaster met with Fr. Khoat in late October 1988 in order to seek evidence on Siri's claim to the Papacy.  In this time frame Fr. Khoat was telling everyone that Siri merely said: It is a secret. 
Hutton Gibson confirms Khoat's changing story.
Fr. Khoat visited Jim Condit in late summer, early fall of 1989.
Fr. Khoat gave a sermon at Saint Jude's Shrine in Stafford, Texas.

The question has arisen whether or not Khoat can be considered credible. This is especially important since he is the only person who testifies that Siri told him that he had been elected.  With Gibson's recent report that confirms the recollections of this webmaster and of other eye witnesses, we can conclude that Tran van Khoat's current testimony must be dismissed is incredible.
Tran Van Khoat's connections with Buddhism.

Will Khoat soon proclaim himself Pope?

I like the position of Archbishop Lefebvre in regard to the Pope.   Fr. Tran Van Khoat March 1989
