"My rivals and I will compete under the same conditions, so I will just focus on my own performance," she said.

Yang's teammate Liu Hong, Olympic champion and world record holder, will also be a contender for the title after the 32-year-old returned to competition from her maternity leave in 2019 in a dominating style, setting a new 50km world record of 3:59:15 in the national championship in March. She still holds the 20km world record of 1:24:38 set in 2017.

Qieyang Shijie is another Chinese walker to watch as the 2017 Olympic silver medallist timed the world's fourth best of 1:25:37 in Huangshan, China.

China's race walk team also eyes the women's 50km glory as Li Maocuo is the fastest athlete on the entry list and former world record-holder Liang Rui is also in good form.

In women's javelin throw, Lyu Huihui has the chance to change her bronze from two years ago into another color in Doha.

Lyu won 12 of her 13 events in 2019 and has held the winning streak since April 9 and produced the world leading throw of 67.98m last month in Shenyang, China.

But Lyu's charge to the title will be by no means an easy one as Australia rising star Kelsey-Lee Barber started the year with a PB of 64.57m but will head to Doha with a personal best of 67.70m, set in Luzern in July.

The men's sprint events will draw huge attention from the Chinese fans as the country's top runners Su Bingtian and Xie Zhenye fight for final berths in their respective event.
