2nd seeded Nehwal beat Sung Ji-hyun of South Korea 21–13, 21–14 to win the Swiss Open title. Nehwal faltered after a good start as she lost to the then world number three Wang Xin of China in the finals to finish runner-up in the 2011 Malaysian Open tournament. She was a part of Indian Team in the 2011 BWF Double Star Sudirman Cup mixed team who managed to reach the quarterfinals of this elite mixed team event for the first time ever, as India managed to beat Thailand 3–2, even when Nehwal lost her tie against Ratchanok Intanon. In the quarterfinals against China, Nehwal put up her best performance and beat the then world number two Wang Xin with 21–15, 21–11, but still the Chinese managed to move into the semi finals with a 3–1 win over India.
