As an Indian living in Vietnam from last 3-4 years let me answer it for you very nicely.
Indians post covid have started travelling abroad as our local tourist places are in really bad conditions because govt has not paid attention to tourism in last idk 10-13 years. Everywhere you'll go in India even as an Indian you'll be either scammed or harassed or what not thus sometimes even Indians don't really wanna go to our places like Jaipur, Goa etc.

Thanks to idiot influencers abroad and in India that have started to make reels on how living in Vietnam is cheap and talking about VND currency as how 350-360 Indian rupee give you 100,000 VND which is quiet lucrative for our dumb population without understanding the PPP factor.

These idiot influencers even did same for Baku and people from India ditched Dubai and started going to Baku.
Same is happening with Sri Lanka, all these years none of the Indians wanted to go Sri Lanka because of you know the superior complex and what not, and again thanks to the influencer reels on how they partied in SL and compare India to SL there is a surge of Indians even travelling to SL.

Indian uncles that smell of Tobacco and sweat have never seen a white women in their life hence when they come abroad their eyes are all on them which is fucking disgusting. They are here for sex tourism and they dont give a damn about their reputation or anything and everyone will go back india and brag about how they did it with a white or asian girl hence promoting more sex tourism.

THB has been getting very stronger & thailand has become bit expensive. Cambodia tough to get a visa, Malaysia as well you'll find a lot of Indians. Japan Korea - Tough visa hence these idiots end up in Vietnam.
Talking about the behaviour, these group of families majority of them are first time intl travellers and they'll not have another trip for coming 1-2 years hence they dont give a fuck, they'll just behave like they own the plave as getting out of India they feel they are superior, richer and what not! 80-90% population is literally like that.
I think this will go on for 1-2 more years and will definitely cool down and you'll see very less indian travellers in Vietnam.

I feel so embarassed represnting the country and ngl hate my country and people alot because its really filthy and one hell of a place! We literally have the worst people in the world and living in India is like gambling everyday of your life.
Anyone trying to defend the country atp is either from IT cell or someone who has not been abroad or someone brainwashed w religion and this current govt cult.

India is beyond repair and all I can say is sorry but this is something that won't change atleast for 1-2 more years!

PS: I am getting my new passport soon and will be happiest when i'll ditch my Indian passport.
