* Euro awaits Greece's 1.2 bln euros bill sale
* ADB recommends "careful capital controls" in Asia

SINGAPORE, April 13 (Reuters) - Asian shares fell on Tuesday ahead of key earnings in the United States while the euro consolidated ahead of a Treasury bill sale by Greece later in the day.
The Nikkei <
> fell as much as 1.09 percent, moving further away from 18-month highs hit last week, as the yen strengthened and investors took profits in chipmakers ahead of earnings from tech bellwether Intel Corp <INTC.O> later in the day. [ ]"Though good earnings are expected, these predictions are factored in, so that anything except a large positive surprise could lead to selling once the results are out," said Takashi Ushio, head of the investment strategy division at Marusan Securities.
The Nikkei's relative strength index (RSI) has fallen as low as 59 after rising to a high of 76 last week. Anything from 70 and above is considered overbought.
Some longer-term indicators such as MACD have turned bearish, with the MACD line now breaking below the signal line, a move seen as a sell signal.
But sharp falls are not expected, with support likely to hold for now near the Nikkei's 25-day moving average, currently at just under 11,000. The index was last at 11,141.30, down 0.98 percent.
The yen advanced on the dollar and the euro, setting off light selling of exporters as well.
The dollar slipped about 0.5 percent against the yen, hovering around 92.8 yen <JPY=>.
Honda Motor Co <7267.T> lost 1.07 percent to 3,250 yen and Sony Corp <6758.T> slipped 1.45 percent to 3,365 yen.
The MSCI index of Asian shares outside Japan <.MIAPJ0000PUS> was down 0.34 percent.
On forex markets, the euro's <EUR=> rally appeared to be short-lived as it hovered around $1.3588, broadly steady from late in New York on Monday, and well below a high of $1.3691 struck in the previous session.
It had jumped after euro zone finance ministers approved a 30 billion euro ($40.5 billion) rescue package of loans, which Greece could tap if needed. At least 10 billion euros are also expected from the International Monetary Fund. [
]Traders had expected the unwinding of euro short positions to support the single currency in the near term, but in the longer term many felt that the bailout package was not a game-changer and the currency would head lower in the next few months.
But a trader at a European bank said the single currency could test $1.37 later the day if a proposed 1.2 billion euros sale of Greek Treasury paper draws a good response. [
]ADB RECOMMENDS CAPITAL CONTROLS
The Asian Development Bank said China's maintenance of limited flexibility in the yuan meant other Asian countries were unlikely to allow their currencies to strengthen.
"To resolve the dilemma, policy coordination among developing Asian countries should be initiated," it said in its annual Asian Development Outlook. [
]"More flexible exchange rate systems are in the region's own interest, and carefully designed capital controls that mitigate disruptive capital inflows may be desirable during the transition to greater flexibility, at least in the short run."
U.S. President Barack Obama met Chinese President Hu Jintao in Washington on Monday and called for more flexibility in the yuan. The Xinhua news agency later quoted Hu as telling Obama that Beijing would "firmly stick" to its own path on the yuan. [
]On metals markets, London's three-month copper futures <CMCU3> fell more than half a percent, extending losses after the market failed to hold on to a rally to a 20-month peak in the previous session on worries that growth in prices have outpaced demand. [
]U.S. crude futures <CLc1> fell for the fifth straight day, edging toward $84, ahead of data due later in the day that is expected to show a build in U.S. crude stockpiles. [
]Spot gold <XAU=> was little changed after a round of physical selling pulled down the precious metal from a four-month high the previous day. [
