BEIJING, Sept 18 (Reuters) - China is willing to

maintain dialogue with all parties involved to keep global

industrial and supply chains stable, its foreign ministry said

on Thursday in response to reports of the Chinese regulator

ordering firms to halt purchases of Nvidia AI chips.

"We have always opposed discriminatory practices against

specific countries on economic, trade, scientific and

technological issues," ministry spokesperson Lin Jian told a

regular press conference without elaborating.
