I've been buying resin or plastic beads like those in your pictures for the past 10 or so years from Chinese, Indian and Indonesian sources. I've seen them in Thailand that I guessed to be either Chinese or Indonesian.

Mohammed Soumareh had some similar a few years ago that he said he got in Kuala Lumpur. Doesn't mean they were made there, just that was his source.

I know that is not a very definitive answer. Fake amber is popular and made in a number of places.
