China said on Tuesday it has noted Japan's positive tone over bilateral ties, but warned Tokyo to stop making indiscreet comments on issues including the South China Sea.

Foreign Ministry spokeswoman Hua Chunying made the remarks after Japanese Foreign Minister Fumio Kishida delivered a speech on Sino-Japanese relations on Monday.

Kishida said he will pay a visit to China. The visit, starting on Friday, will be his first formal visit to the country since the administration of Shinzo Abe took office in December 2012.
