Su, who led China to silver in the men's 4x100m relay at the 2015 Beijing world championships, added: "In the past four years, Chinese sprinters have made great improvements but we only lack a medal from individual events. Today the dream has come true.

"My next goal is to reach the 100m final at the Olympic Games. I will make more efforts and hopefully I can make it at Tokyo two years later."

Coleman rose to prominence last year by winning 100m silver at the world championships and last month smashed Maurice Greene's 20-year-old 60m world record by clocking 6.34 seconds.

The 21-year-old came within 0.03 sec of that mark at Arena Birmingham, but he was just glad to take gold.
