Tibet flag display causes China U-20 side to walk out of first match in Germany

The match had to be delayed for 25 minutes after fans of TSV Schott Mainz unfurled a flag of the disputed region

China's U-20 side walked off the pitch during their first match in Germany after TSV Schott Mainz fans revealed a Tibet flag.

The friendly was delayed for 25 minutes before fans agreed to put the flag away, resulting in the Chinese side returning to the pitch.

The China U-20 team was controversially included in the fouth-tier Regionalliga Sudwest this season after just 19 teams qualified for the league.

Needing to fill up the teams' fixture list, the side was added as part of a five-year agreement between Germany and China with the aim of improving Chinese youth football.

Three of the league's 19 teams have refused to take part in the arrangement, with the other 16 teams set to face the Chinese youth side in a friendly during the second half of the season.
