China sent medical aid and supplies to EU countries affected by the COVID-19 pandemic. EU foreign policy chief Josep Borrell warned that there is "a geo-political component including a struggle for influence through spinning and the ‘politics of generosity’." Borrell also said that "China is aggressively pushing the message that, unlike the US, it is a responsible and reliable partner." During the 2020 China-EU summit, European Council President Charles Michel stated that "Europe is a player, not a playing field" regarding its relationship with China. In December 2020 the EU announced that the Comprehensive Agreement on Investment was concluded in principle. Some analysts said the Agreement may damage relations with the US.
