Hong Kong - The Springbok Sevens team easily won their two Pool E matches on Saturday against Hong Kong and Wales to advance to the quarter-finals of the Hong Kong Sevens.
South Africa will face Fiji in the last eight on Sunday, the third and final day of the tournament.
New Zealand play Portugal, Samoa are up against Australia, and Russia, who reached the Cup quarter-finals for the first time, take on England.
Two tries from Paul Delport and Sibusiso Sithole and one for Sevens debutant Tshotsho Mbovane ensured South Africa topped Pool E at the end of day one after a 42-12 victory against Wales.
Earlier, the US Sevens champions inflicted defeat on Hong Kong as they ran out eventual 45-0 winners against the hosts. Cecil Afrika and Chris Dry both scored two tries.
On Friday the Blitzbokke had beaten Spain 33-5 in their opening fixture of the tournament, the fifth stop of the HSBC Sevens World Series.
"I'm really pleased with the overall effort today, especially our display against Wales," Treu said.
"The real business only starts tomorrow (Sunday) morning in the quarter-finals and our aim will be to keep our focus and our composure and to keep the momentum.
"I'm also very glad that Tshotsho Mbovane could score his first try in his first tournament.
"This is a special tournament and he will remember it for a long time."
With 24 teams in the draw for the tournament split across six pools, only the winner in each group will be guaranteed a place in the Cup quarter-finals on the third and final day.
They will be joined in the last eight by the two best runners-up.
