The main theme of the conference is "Towards a Common Future", FO said.
India will walk the diplomatic tight rope this week during Prime Minister Narendra Modi's visit to the Commonwealth Heads of Governments Meet (CHOGM) in London as the United Kingdom looks for support from the 53 member grouping in bringing out a strongly worded statement slamming Russian Federation for the alleged use of a lethal nerve agent on British soil. Yet risks remain. Global growth is fragile. The Commonwealth's various constituencies - the Commonwealth Secretariat, its members or its myriad of organizations and networks - mean it is uniquely placed to respond to these challenges.
PM Lee arrives on Wednesday (April 18) for the two-day meeting on Thursday and Friday, and will hold bilateral talks on the sidelines with other Commonwealth leaders. India's trade with Commonwealth nations is 20 per cent of its global trade basket.
At the meeting, leaders are expected to discuss global and regional issues of concern, such as weak global trade and investment flows, and the effects of climate change on small and other vulnerable states, and review developments in the Commonwealth.
Chandrajit Banerjee, CII Director-General, said: "The key question is what will be the new-age "common" factor in the Commonwealth?"
He stressed that re-engaging with the Commonwealth at the highest level with Prime Minister Modi's participation at CHOGM later this week is a marked strategic shift for India.
International Development Secretary Penny Mordaunt said: "The scourge of plastics is a global environmental challenge - and one that overwhelmingly impacts the livelihoods and health of the world's poorest people".
The UK will also fund a new Trade Facilitation Programme, supporting and providing technical assistance to selected Commonwealth countries in implementing the World Trade Organisation's Trade Facilitation Agreement.
