Moody downgrade China's rating

China's great wall of debt! Moody's has lowered the nation's credit rating to A1 from Aa3, citing Beijing's waning financial strength and rising liabilities. It marks the first time a major ratings agency has downgraded the country in more than 25 years. The move also received a backlash from China's finance ministry, which said the decision was "absolutely groundless" and was based on an "inappropriate calculation method."
