ASIA SHINE ON BEIJING , OIL AND DOLLAR INDEX POSITIVE

• On Tuesday , Asian Indices shining on Beijing in trade talks with Washington added to other recent signs of progress, fueling a rally in Wall Street's main benchmarks to record highs.

• A quick resolution to the U.S.-China trade war is far from certain, because relations between the world's two-largest economies have often been acrimonious and negotiations have stalled many times before. If both sides cannot reach an agreement soon, the next important date to watch is Dec. 15, when Washington is scheduled to impose even more tariffs on Chinese goods.

• Wall Street's three main stock averages closed at a record high on Monday, buoyed by hopes for a trade deal and by M&A activity in luxury goods and online trading.

• Traders pointed to China's decision to increase punishments for intellectual property rights violations as a fresh concession to the United States in the drawn-out and volatile negotiations.

• Investors were also encouraged by positive comments from U.S. President Donald Trump, Chinese President Xi Jinping and Chinese state-owned media about the chance for an imminent trade deal.

• The yen eased to a one-week low versus the dollar, while the Swiss franc traded near a six-week low against the greenback as the optimistic tone sapped demand for safe-haven currencies.

• The yen fell to 109.04 per dollar, the lowest since Nov. 18, as safe-haven demand waned.

• The Swiss franc , another safe-haven, traded at 0.9970 per dollar, close to the lowest since Oct. 16.

• Elsewhere in the currency market, sterling traded at $1.2898, holding onto overnight gains as polls show the ruling Conservatives as runaway favorites to win a Dec. 12 election with a pledge to implement Britain's divorce from the European Union.

• Oil prices gave up some gains in Asia in a sign that some investors remain cautious about the prospects for a lasting agreement to remove perhaps the biggest risk to the global economic outlook.

• U.S. crude dipped 0.07% to $57.98 a barrel in a sign of some investor caution. However, further declines could be limited before data this week forecast to show a decline in U.S. crude oil inventories.

• In addition, the Organization of the Petroleum Exporting Countries (OPEC) meets on Dec. 5, where the bloc is widely expected to extend supply cuts to mid-2020.
