The vessels were released, but the crews were not, it's in the report, can't you read? Apparently it's all goes down to wE wUz EaST AsiANs rhetoric, pointing out irrelevant things like eating by hand, pathetic little brat has a knack for racism isn't it? Now the topics shifted to Viet indirectly flashing their chopstick culture nobody cares about, and now they use "Khmer" as improvised slur word, their short sighted view on things will result in their spectacular failure eventually.
Now, the card "Barbarian" have been used, a Confucian culture themed term to be used to refer to all non Sinosphere cultures, and it's used by the bastard child of Chinese cultural influence, a people not recognized as equal to every other established sinosphere countries, or in other word, self proclaimed east asian too bad to actually be inside the club, but desperate enough for identity and acknowledgement to claim as such.
The method which used to support their east asian muh superiority complex rhetorics is "oh yeah, just like Cambodia", "oh yeah just like the Khmers", "oh yeah i'm so delusional to think my shallow arguments matters". There's no need to hype oneself, especially if you are Vietnamese, as it will certainly result in disappointment and bitterness. If China is a person that have two child, let's say one Vietnamese boy and one Mongol girl, and can only pick one due to the one-child policy, she would certainly just throw the Vietnamese away into the dirt without hesitation.
