Ultimately China can say no. Why she doesn't say no?Other research paper stated that China contribute 16% of Mekong water, but this is almost similar to the 13.5% that China MoF claimed.
When Vietnam in drought, she beg China. Despite having very little catchment, China release the water for Vietnam.
Why beg China? Why not beg Laos? Lao contribute to most catchment.
Reason is China has a lot of dam while Laos has not so much. So only China can help. Lao cannot help.
No thank you note from this PDF @Viet guy.
