A repeat of last year's men's World Championship final remains on the cards at the All England Badminton Championships as both Kento Momota and Shi Yuqi reached the last four.
Japan's world champion and top seed Momota kept his hopes of a maiden title alive at Arena Birmingham as he saw off India's seventh seed Srikanth Kidambi 21-12, 21-16 on quarter finals day.
Shi, the second seed and defending champion at the prestigious Badminton World Federation World Tour 1000 event, also advanced as the Chinese beat unseeded Japan player Kanta Tsuneyama 21-14, 21-7.
Momota will now play Hong Kong's unseeded hope Ng Ka Long in the last four who came from behind to knock out Indonesia's Tommy Sugiarto 16-21, 21-14, 21-15.
Former world champion Viktor Axelsen will meet Shi after the Dane took care of his compatriot Jan Ø. Jørgensen, 23-21, 21-18.
In the women's competition, Chinese Taipei's top seed Tai Tzu-ying remains on track for a third All England crown in a row.
She knocked out India's eighth seed Saina Nehwal 21-15, 21-19 and will now play Japan's fourth-ranked Akane Yamaguchi.
The Japanese player won a tight tussle with China's sixth seed He Bingjiao, 21-16, 19-21, 21-12.
Japan's second seed Nozomi Okuhara is also through as the 2017 world champion knocked out China's unranked Li Xuerui 21-17, 21-14.
