Zhan was set to make his debut in the tournament which starts on Thursday alongside Xiaochen Zong but due to passport issues, that is no longer possible.
This means that Liu will make his third appearance in the World Cup of Darts.
He has also previously played in the World Championship and World Series events and will form part of the lineup when China face USA.
