“Premier Li Keqiang added his voice to concerns that the world’s biggest economy could default on its debt.  Mr Li told John Kerry, US secretary of state, that China was paying ‘great attention’ to the issue of raising America’s $16.7 trillion (£10.5 trillion) debt ceiling.  China is the largest foreign owner of US debt, holding more than $1.277 trillion in Treasury bills.  Mr Li’s remarks, published by the state-owned Xinhua News Agency, follow comments by vice finance Minister Zhu Guangyao on Monday that ‘the clock is ticking’ and any US default would have global repercussions.  Mr Kerry [is said to have] made clear to Mr Li that President Barack Obama was ‘committed to resolving the issue.'”
