The pairing, who play in the Wimbledon women's doubles semi-finals on Friday, say their partnership is all about firm friendship -- and they leave the political stuff to others.
Peng and Hsieh, born four days apart in January 1986, have been mates since their junior days and won the first of their five tour titles together back in 2008.
Their closeness has endured and the warmth between the 27-year-olds is obvious, with the pair constantly laughing and joking in each other's company.
Hsieh added: "She plays most of the court and I stay by the sidelines! She's working very hard. We enjoy it.
"If we don't fight there will be no problem!", she joked.
Peng said: "We speak the same language and we've known each other and been friends since we were young. We have fun and we really enjoy our tennis.
Taiwan and China have remained technically at war since Taiwan split from the mainland in 1949 at the end of a civil war. The island still styles itself the "Republic of China". Beijing considers Taiwan part of its sovereign territory and insists that the two entities must eventually reunite, by force if necessary.
