Indeed, Malay Can Become Asean's Lingua Franca if every ones in the region feel that it's a better, if not best, communication language than some of the established international languages like English, French, German, and even Japanese or Korean was once widely promoted. However, the process of transition will take time, and through stages of evolution.
It'd be disappointing attempt if the ambition is built from pure racialism, and so-called regionalism, as great culture usually did not emerge in one day.
While the language users, academicians, and promoters are still hard at work to produce Malayu words that trying to match up with the pace of technology advancement, and the rapidly changing world, we must admit that our language is still very much in state of struggle that we seem are seen chasing others than being followed.
We should be in reality pursuing nationalism, or regionalism, while putting equal effort in internationalism.
