I am going to visit many Asian countries. Below are the countries I wanted to visit. I wanted to know are any of these countries unsafe and have lots of crime?

Malaysia
Sri Lanka
Japan
Thailand
Laos
Philippines
Cambodia
Singapore
Vietnam
Papua New Guinea
Bangladesh

Also, before I go, I wanted to be able to speak some of the languages. Which language do these countries speak or do they all speak different languages? Is there 1 language which many of these countries speak?

"5" star boutique hotels or best accomodations, eco lodges, local markets, meet local people, good food, culture sites, suggest itineraries, highlights. Starting point Hanoi, ending Cambodia. Plan to hire driver/guides with excellent references and command of English language:(suggestions ?), take boats and trains. Any and all suggestions welcomed. We are seasoned world travelers and love to "wing it", get lost, explore, take millions of photos and mostly avoid other tourists ! Please don't send me shopping; I'll do that in Paris !
Thanks all !

The Spaniards have affected the Philippines culturally and linguistically, but it seems like the former nations of Indochina (Vietnam, Laos, and Cambodia) have managed to get rid of French influences.

What from the French has remained in any or all of these nations? Language, traditions, culture?

I feel shamed to ask "Do you know Thailand ?" I am Thai. I found that Vietnamese and Indonesia language are available in Google translation machine but Thai. I think in South East Asia several countries such as Laos Cambodia Singapore Myanmar Vietnam Malaysia and China support studying Thai language. However, There are not much programs to promote study Thai or other applications for instance translation, dictionary, reading machine or OCR.
When I register the websites, they want me to inform the language but there is no Thai provided. What happened? Maybe my language is a minority of world language use.

Hey everyone,

I'm writing an essay on the Watergate scandal and I have to talk about the Vietnam War since it leads to the Pentagon Papers and the eventually cover up of the burglary to steal those papers.

I came across a section in a book that reads Cambodia was a neutral territory but before it states that the North Vietnamese had "safe" havens inside the country.

Could somebody please help me understand this? Thanks in advance.

I know this is an odd question, but I'm planning a trip to Vietnam and Thailand and looking to stop in Cambodia while I'm there but I would like to learn the language before I do. So I wanted to know is there a universal dialect used, like if I learn Vietnamese I'll be ok in all three places or do I need to learn a different language in all three countries, thanks in advance!
