Have a read, and comment. Kudos for someone making a list.

For most of us, Petronas is just another Malaysian GLC – one that we see every day, and possibly even give business to on a regular basis – same la… like Unifi, or Tenaga Nasional.
However, you don’t see your former PM geting booted off the board on those other companies.
In fact, Petronas has been in the news recently for cutting 1000 staff, and needing to borrow money! But aside from being Malaysia’s only oil and gas company, what makes Petronas so special, and so important to Malaysians? As we started exploring, we realised one thing – there’s ALOT we don’t know about Petronas, and we should. Why? Because it supplies around 30% of our GDP. Yep. One company pays for 30% (some even say 40%) of Malaysia.
If that blew your mind, wait till you see what else we found out…

PETRONAS is also driving large scale and prestigious projects such as the world’s first Floating LNG platform. I write about it in my blog.
