BEIJING, June 21 (Reuters) - China's commerce ministry said on Thursday the European Union has continued to escalate trade friction, which "may trigger a "trade war."

"Responsibility lies entirely with the EU side," a ministry spokesperson said in a statement.

China hopes the EU will meet it halfway, handle difference through dialog and avoid escalating trade friction or allowing it to get out of control, the spokesperson said. (Reporting by Ella Cao, Ethan Wang and Ryan Woo; Editing by Christopher Cushing)
