Of course the cancelling of the LNG project has nothing to do with economics but everything with politics. Even if Petronas after spending some hundreds of millions says otherwise .  Is all Fake News I guess.
The same faith might be in store for the XL pipeline. Presently the owners of of that project are looking for long term delivery contracts from buyers. So far not enough takers. If they do not get them who knows if it makes any economic sense.
