Saudi Arabia has announced that it will place a 50% levy on sweetened beverages such as soft drinks and a 100% tax on energy drinks and cigarettes as it looks to boost revenue amid falling oil prices.

The new taxes were first proposed by the Gulf Cooperation Council (GCC) last December, but Saudi Arabia recently signed the agreement.

The country said that the increases are part of an “excise tax on harmful products”. The taxes will come into effect in April 2017.
