China's quadruple World Championship gold medallist, the winner in 2016, demolished Belarus player Vladimir Samsonov in straight games at the resort in the French capital.

The world number one won 11-3, 11-6, 12-10, 11-6 against the 15th seed to reach the last four.

"I had to control the match and concentrate at all times," said Fan.

"Vladimir is a top player and it's always a pleasure to play against him. 

"He has excellent tactics, so I always have to respect him."

All of the top six seeds made it through to the last eight on a busy day of action which also saw the last-16 clashes played.

Germany's defending champion Dimitrij Ovtcharov, seeded third, won an epic against fifth-seeded South Korean Lee Sang-su.

The European player triumphed 11-7, 11-5, 11-13, 9-11, 5-11, 11-5, 11-5.

That has set-up an all-German semi-final as second seed Timo Boll also advanced, beating fifth seeded Japanese player Tomokazu Harimoto in five.

Boll, the second seed, knocked out the 15-year-old sensation 9-11, 11-3, 13-11, 11-5, 11-9.

Fan will meet his compatriot Lin Gaoyuan in the semi-finals, the fourth seed.

Lin ended the hopes of Japan's Koki Niwa in the last eight, 12-10, 5-11, 14-12, 11-9, 11-5.

Both the semi-finals and finals will be played tomorrow.
