"I love playing singles," said Venus. "It just happens with my schedule now that I don't get as much opportunity. [But] I've played on this court all the time and I'm confident going out there."
Venus has played just 10 singles matches since the beginning of the 2016 season, and only two this year.
New Zealand No1 Rubin Statham (world No408) is in good form, after what he describes as the "best start to a year in my career". He went close against Jiri Vesely in the second round of the ASB Classic - after getting through as a lucky loser - and has reached two Futures final in China, winning one.
Korea have a weakened side, with the absence of their top two players who are focussed on French Open preparations, but won't be pushovers.
The winner of the tie will seal their place in Asia/Oceania Group 1 while the loser faces a relegation battle later in 2017 to stay in the group.
