China wonders: Why do we own so much U.S. debt?
In the highest-level statement to date by China, Chinese Premier Li Keqiang has weighed in on the U.S. debt ceiling debate.
At a meeting on the sidelines of a summit in Asia, Premier Li told U.S. Secretary of State John Kerry that China was paying "great attention" to the political gridlock in Washington.
Chinese officials have voiced their concerns over the impasse, worried the stalemate could trigger a debt default.
Earlier this week, Zhu Guangyao, vice finance minister, warned that the "clock is ticking" in reference to the Oct. 17 deadline to lift the debt ceiling in the U.S. He urged the U.S. to "ensure the safety of Chinese investments."

So far, there are no signs China is selling its U.S. Treasurys.
However, some bond traders point to data out of Japan as an indication of market jitters due to the debate in D.C. Data released by Japan's Ministry of Finance show Japanese investors sold foreign bonds at record levels last week, at nearly $23 billion dollars.

In addition, Hong Kong's exchange decided Thursday to value U.S. Treasurys lower, in the first sign in Asia of authorities preparing for the possibility of the U.S. government defaulting on its debt.
The Hong Kong Exchanges & Clearing (HKEx) said it's applying a discount or a "haircut" to the valuation of T-bills used as collateral against future trades.
