Sri Lanka has imposed a ban on palm oil imports and ordered planters to cut down all palm trees in the country, replacing them with rubber or environment-friendly crops. The president has also directed the Director-General of Customs to cease clearing palm oil cargoes. The decision comes amid similar bans by the US and EU over allegations of forced labour and unsustainable practices. However, the ban could be challenged under the World Trade Organization's non-discrimination principles. The government may review the order, and the review mirrors the government's decision to ban the cultivation of GMO crops in 2013.
