Why do many Asian demonyms end in "-ese" (ex: Burmese, Vietnamese, Japanese), while many Western Hemisphere demonyms end in "-an" (ex: American, Mexican, Chilean)? Why don't we say Americanese, or Vietnaman?

The -ese ending is hardly limited to Asia. There are Sudanese and Portugese, to name two.

The ones ending in -*ese* in English actually come from Italian. Recalling that Marco Polo and other Italian traders were the first Europeans to reach the Far East, it should be no surprise.
