“It’s always great to have these tournaments for our Cambodian juniors, despite them having a tough time in the qualifying rounds, it exposes them to a high level of tennis that they can’t always get throughout the whole year,” said Tennis Cambodia secretary-general Tep Rithivit.

“I really want to thank sponsors, ABA Bank and Pharmacie De La Gare for their continued support to run these events – it is a vital event to have for the pathway of our juniors here in Cambodia,” Rithivit added, hinting that two more similar events are being planned before the end of the year.
