European Union and Chinese leaders kick off a summit Tuesday at a time of global uncertainty over Brexit and pressure from European companies for better access to China's market.

EU leaders are expected to press their Chinese counterparts to accelerate their efforts to reduce overcapacity in sectors including steel amid complaints in Europe that low-cost Chinese competition is putting European steelworkers' jobs at risk.

President Xi Jinping and Premier Li Keqiang will meet with European Council President Donald Tusk and European Commission President Jean-Claude Juncker on Tuesday.

Also high on the agenda during the two-day summit in Beijing will be a push for progress on an investment agreement between the two sides. The EU says this is to enable fair competition between Chinese and European companies.
