China's top government auditor pledged on Friday to keep a close eye on the levels of debt and spending to ensure the country's fiscal stability.

Liu Jiayi, head of the National Audit Office, said that his office will track the potential risks of accumulated debt and how they are dissolved, while checking how new debt is used.

The office will also audit officials in "key regions, key departments, key agencies and key posts" at least once during their terms, and conduct checks of government spending on conferences, meetings and office buildings, he added.
