Iron ore and steel futures in China jumped on Thursday, extending gains into the fourth straight session after Beijing pledged more stimulus to relieve tax burdens and boost credit support for companies.

In a cabinet meeting led by Premier Li Keqiang on Wednesday, the government said it will further extend tax cuts for small firms and create policy tools that will enable banks to issue more unsecured loans, Chinese state television reported.

China also aims to issue another 1.0 trillion yuan ($140 billion) worth of local government special bonds by the end of May, according to the cabinet meeting.
