Petroleum trade unions have threatened an unannounced strike next week, if their demands are not met by May 22. 

Issuing a statement a collective of Petroleum trade unions reminded the government they had suspended their trade union action on April 24 on the promise a solution to their demands would be made.

The Petroleum trade unions are protesting the Sri Lanka government’s impending deal with India, to develop the WWII-era oil tanks in Trincomalee.

Their strike on April 24 was called off after discussions with Prime Minister Ranil Wickremesinghe. 

More recently, both the President and the Prime Minister assured the public they would not enter into any agreement with India during Indian Prime Minister Narendra Modi's visit to Sri Lanka on account of Vesak Day. 

This assurance comes despite several deal with India in offing: These include the Economic and Technological Corporation Agreement and the pending agreement to develop the Trincomalee Port.
