The euro fell against other major currencies in Asia on Monday as investors awaited further details on measures to tackle the Eurozone debt crisis following an EU summit deal struck last week.

The euro bought $1.3340 and 103.57 yen in Tokyo afternoon trade, down from $1.3384 and 103.93 yen late Friday in New York, where the common European currency rose on the tentative fiscal pact struck by European Union leaders.

Oil weakened in Asian trade Monday as investors remained cautious despite European leaders announcing a deal aimed at saving the Eurozone, analysts said.

New York's main contract, light sweet crude for January delivery, dropped 25 cents to $99.16 a barrel and Brent North Sea crude for January delivery fell 39 cents to $108.23.

Thousands of Italian women rallied on Sunday, demanding greater rights and an end to discrimination and blaming the country's "macho culture" for its current crisis.

The head of China's central bank says the country will implement changes to its financial system suggested by the International Monetary Fund "as appropriate", the Washington-based lender said.

British Prime Minister David Cameron faced searching questions Saturday over his veto of a new EU treaty to solve the Eurozone crisis, despite receiving a hero's welcome from his party's lawmakers.

Japan is extending tax breaks for low-polluting vehicles by another three years to help support the nation's mainstay auto industry.

The tax breaks, initially set to end in April, will continue until April 2015, according to a plan approved by the Cabinet on Saturday.

China's exports slowed in November, data released Saturday showed, raising the likelihood of further measures from Beijing to help prop up faltering growth and offset slack demand in the U.S. and European markets.

Exports rose 13.8 percent to $174.5 billion in November, a decline from 15.9 percent growth in October, while China's overall trade surplus plunged 35 percent from a year earlier, to $14.5 billion, Customs statistics said. Imports gained 22.1 percent to $159.9 billion, down from the previous month's 28.7 percent rise.

The leaders of 23 European countries moved to tie their economies much closer together in a new treaty in their latest attempt to shore up the euro, but failed to get the four other European Union members, including Britain, to join in.

Following marathon all-night talks, the 23 decided to back a new treaty with strict oversight over national budgets, as they try to convince markets that the euro has a future in the wake of a crippling debt crisis.

Republicans and Democrats determined to look tough on Iran and avoid any election-year challenges to their pro-Israel bona fides are rebuffing Obama administration pleas to ease proposed penalties on Iran's central bank.

The administration argues that the crippling penalties would undercut a carefully calibrated international effort targeting Tehran and would drive up oil prices, a potential economic boon that would help finance Iran's suspected pursuit of a nuclear weapon while hitting cash-strapped Americans at the gas pump.

Toyota slashed its full-year net profit forecast on Friday by more than half as Japan's biggest automaker grapples with a strong yen, the impact of the March earthquake and record flooding in Thailand.

The company cut its profit outlook to 180 billion yen ($2.3 billion), well down from its August estimate of a 390 billion yen net profit, which was pared after the Thai floods forced plant closures and caused supply-chain problems.
