Asian markets have dropped in the morning session as concerns on the US "fiscal cliff" and eurozone conditions offset the relief from the conclusion of America's presidential elections.

Japan's Nikkei slid 1.25 percent or 112.02 points to 8860.87 at 02:44 GMT while South Korea's KOSPI tumbled 1.28 percent or 24.74 points to 1912.81.

Hong Kong's Hang Seng fell 1.10 percent or 242.90 points to 21856.95. China's Shanghai Composite Index was down 0.66 percent or 13.94 points to 2091.79.

US markets had closed with heavy losses overnight, as investors looked beyond Barack Obama's victory to the economic challenges that confront him.

"The relief rally Wall Street experienced in the election run-up quickly reversed as the cold, hard realities of an economy on the edge of a $600bn precipice set in," said Justin Harper, market strategist at IG Markets.

The news from across the Atlantic also failed to offer encouragement. The Greek coalition government was able to get a fresh set of austerity measures approved by parliament, but the margin was so narrow that concerns on the country's stability remain.

Protests against the government's cutback plans continued, with a 48-hour strike by public and private sector workers ending in violent clashes between demonstrators and the police in Athens.

Traders in Japan were discouraged by domestic issues. Official data showed that the country's machinery orders fell more than expected in September, while its current account surplus narrowed by 69 percent.

Investors are also keeping a close watch on China where a once-in-a-decade leadership change is set to take place later in the day. Speculation is mounting over how the new regime will address the issue of the country's slowing economy amidst the global downturn.
