European Commission President Jose Manuel Barroso arrives in Nanjing, capital of east China's Jiangsu Province, Sunday noon.
He was in Nanjing to attend the 12th China-European Union (EU) summit, due to be held Monday morning.
Swedish Prime Minister Fredrik Reinfeldt, whose country currently holds the rotating EU presidency, will arrive in Nanjing later Sunday.
Chinese Premier Wen Jiabao, Barroso and Reinfeldt, will co-chair the one-day meeting, which is believed to focus on Sino-EU relations and other global issues, including economic recovery and climate change.
The China-EU summit is the highest level political consultation mechanism between the two sides.
