(CNN) -- Asian and Pacific stock markets sank in early trade on Tuesday after the U.S. House of Representatives failed to adopt a financial bailout plan, which triggered the largest point drop in U.S. market history.

Many of the markets expanded their losses toward the end of the trading day.

As it became apparent the vote was lost, the Dow Jones plunged.

Monday's plummet knocked out approximately $1.2 trillion in market value, the first post-$1 trillion day ever, according to a drop in the Dow Jones Wilshire 5000, the broadest measure of the stock market. However the 7 percent decline does not rank among the top 10 percentage declines.

Republicans and Democrats blamed each other for the result -- 205 to 228 against the bailout.

President George W. Bush was "very disappointed," his spokesman, Tony Fratto said. Bush will be meeting with his advisors and will be calling congressional leaders, Fratto added.

Treasury Secretary Henry Paulson said he will continue to work with congressional leaders to draft a plan that does pass.

Before the vote, Bush said the plan was of "tremendous importance to all Americans." Bailout explainer: What's in the bill?

The Democratic candidate for U.S. president, Sen. Barack Obama, blasted Congress for not passing a financial rescue package, while the Republican candidate, Sen. John McCain's campaign accused Obama and Democrats of putting "politics ahead of country."

A four-hour debate included impassioned pleas for and against the measure from Democrats and Republicans alike. Even some of those arguing for the legislation were quick to point out problems with it.

But the vote began with both Democratic and Republican leadership telling their members the only way to protect the economy from a spreading credit crunch was to vote for the difficult to swallow measure.

After the defeat, Republican leaders accused Nancy Pelosi, the Democratic speaker of the House, of giving a partisan speech which "poisoned" Republican support. Watch Republicans lay the blame at Democratic feet »

Pelosi said the $700 billion "is a number that is staggering, but tells us only the costs of the Bush administration's failed economic policies."

But Barney Frank, the top Democrat on the House Financial Services Committee, demanded: "Because somebody hurt their feelings, they decided to punish the country?" He said he did not think the Republican leadership was able to get enough colleagues to support the bailout and was diverting attention to Pelosi.

When leading House Republicans signed on to the proposal Sunday after earlier reservations, the bill was expected to pass.

Governments, markets and businesses around the world were watching developments in Washington closely amid fears that failure to tackle the crisis on Wall Street could have disastrous repercussions for the entire global economy.

The U.S. bailout bill, released Sunday and endorsed by Bush after days of intense negotiations, is based on Treasury Secretary Henry Paulson's request for authority to purchase bad debts from financial institutions so banks can resume lending to enable credit markets, now virtually frozen, to resume operating normally.

Concerns among some politicians over potential costs to taxpayers led to several amendments inserted to protect them from risk while giving them a chance to share in any profits if companies on Wall Street benefit from the plan.

Pelosi said Sunday the provisions added by Congress -- which include a restriction on salary packages for senior executives whose companies benefit from the rescue plan -- will protect taxpayers from having to foot the bill for the bailout.

The aim of the rescue plan, which Paulson has been pushing since September 18, is to unfreeze the credit markets -- short-term lending among banks and corporations. The core of the problem is bad real estate loans that led to record foreclosures when the housing bubble burst and home prices declined.

In the past two weeks, the banking world and Wall Street have been reordered by a wave of collapses and corporate mergers.
