A Beijing court says a businesswoman linked to China's fallen ex-railway minister has been convicted of bribery and sentenced to 20 years in prison.

The Beijing No. 2 Intermediate People's Court said Tuesday it had also convicted Ding Yuxin of illegal business operations in relation to her helping 23 companies win the bidding for 57 projects. For this, she personally received 2 billion yuan ($330 million).

The court said that between 2004 and 2011, Ding offered then-railways boss Liu Zhijun some 49 million yuan in kickbacks.

Liu, known as the driving force behind China's bullet train network, was convicted last year of taking bribes and steering contracts to associates.

Ding was also fined 2.5 billion yuan ($410 million) and had assets worth 20 million yuan ($3 million) seized.
