Sept 2 (Reuters) - China has warned severe economic

retaliation against Japan if it further restricts sales and

servicing of chipmaking equipment to Chinese firms, Bloomberg

News reported on Monday, citing people familiar with the matter.

Toyota Motor ( TM ) privately told Japanese officials that

Beijing could react to the curbs by cutting Japan's access to

minerals required for automotive production, the report said.

Several Chinese officials had repeatedly outlined the

position with their Japanese counterparts in recent meetings,

the report added.

Toyota ( TM ) and the Chinese foreign ministry did not immediately

respond to Reuters' requests for comment.

Japan began restricting exports of 23 types of semiconductor

manufacturing equipment, aligning its technology trade controls

with a U.S. push to curb China's ability to make advanced chips

in July.
