Hi all, I'm from Vietnam and i'm comeback Vietnam from Laos yesterday. The last week, i had a plan to go Laos, Thailand, Cambodia by my motorcycle. When i crossing to Thailand from Laos at Vang Tao Chong Mek border, The immigration officer (captain) refused me crossing to Thailand, he has explain for me because Thailand and Vietnam is not sing contract transportation, so in this case he just only welcome man, is not the motorcycle. I said, OK. I don't care Vietnam and Thailand have sing contract transportation, but Vietnam anh Thailand is Asean...Unbelieve, he said ! Vietnam not yet... And I showed, i had crossing to Thailand in this border on the May 2010, he said the frist time is OK. is not the second time will be OK. Finally, he refused me into Thailand and recommend with me is try another border...funny? I don't understand him, maybe he is sick.
