The Chinese star headed into the final on a high in Hungary’s capital city, having beaten defending champion Ding Ning and earned the mixed doubles crown with Xu Xin yesterday.

Liu, the fourth seed, lost the opening game of the gold medal match against her compatriot Chen Meng.

She hit back in impressive fashion at the Hungexpo venue by winning the next two games, only for Chen to immediately level.

But Liu edged out the second seed, the 28-year-old claiming consecutive games to secure a 9-11, 11-7, 11-7, 7-11, 11-0, 11-9 victory.

Bronze medals were awarded to Ding and Wang Manyu, following the Chinese players' defeats in the semi-finals.

The men’s doubles final saw China’s Ma Long and Wang Chuqin emerge winners.

The duo combined to impressive effect to beat Romania’s Ovidiu Ionescu and Spain’s Álvaro Robles 11-3, 8-11, 11-7, 11-3, 11-5.

Ma then progressed to men’s singles final, with the two-time defending champion overcoming compatriot Liang Jingkun.

The Olympic gold medallist won 11-8, 6-11, 11-9, 11-9, 14-12.

He will now face Mattias Falck, who became the first Swedish finalist since the great Jan-Ove Waldner triumphed in 1997.

Falck beat the unseeded South Korean An Jae-hyun 8-11, 11-7, 11-3, 11-4, 11-8, 2-11, 11-5.

He becomes the first non-Chinese player to reach a gold medal match since 2003.

The women’s doubles semi-finals will also take place, with a meeting of Chinese and Japanese pairings guaranteed for the final.

Top seeds Mima Ito and Hina Hayata will face Honoka Hashimoto and Hitomi Sato in an all-Japanese semi-final.

The winners could face second seeds Wang Manyu and Sun Yingsha, who face Chen Meng and Zhu Yuling in an all-Chinese clash.
