As is the usual in these cases, Disney has denied showing any interest in building a new themepark in Malaysia.
"We are constantly exploring opportunities
around the world as we look to grow our parks and resorts business. At
this time, however, there are no existing discussions in Malaysia and
we currently have no plans for a Disney-branded resort development in
that country," Lisa Haines, worldwide public affairs vice president for
Walt Disney Parks and Resorts, said in a statement.
So it’s not likely we’ll see a Disneyland Malaysia anytime soon. However, there is some wiggle room in that statement. Disney could build a themepark, just not a Disney-branded one. (link)
