US president Barack Obama has hailed the Northern Ireland policing and parades deal as an important step on the path to greater peace and prosperity.
First Minister Peter Robinson, deputy First Minister Martin McGuinness and Taoiseach Brian Cowen will meet Mr Obama at the White House on St Patrick's Day to discuss progress.

"The president appreciates the personal contributions and steadfast support of the Taoiseach and UK Prime Minister Gordon Brown in support of the historic agreement achieved by Northern Ireland leaders today, which is an important step on the pathway to greater peace and prosperity for all communities on the island," a White House statement said.
"The president looks forward to commemorating his second St Patrick's Day in the White House with the Taoiseach, a celebration which serves as a reminder of the shared history and close kinship between our two countries," the statement added.
The deal agreed by the DUP and Sinn Fein will see policing and justice powers devolved from Westminster on 12 April.
On Friday, the settlement was unveiled by the First and Deputy First Ministers and the two Premiers at Hillsborough Castle, Co Down, where the parties held nearly two weeks of marathon talks.
'Dividends'
US secretary of state Hillary Clinton has also praised the settlement.
"Northern Ireland has taken another important step toward a full and lasting peace", Mrs Clinton said.
"The accord they reached will help consolidate the hard-won gains of the past decade".
"In finalising this deal, Peter Robinson and Martin McGuinness and their teams displayed the kind of leadership that the people of Northern Ireland deserve."
Mrs Clinton said the United States were committed to "help Northern Ireland reap the dividends of peace, including economic growth, international investment, and new opportunities."
It is understood the NI leaders will discuss further investment in the region as part of their visit to Washington next month.
Last October, Mrs Clinton met with MLAs, business and civic leaders in her seventh visit to Northern Ireland since she first arrived as First Lady with her husband President Bill Clinton to boost the fledgling search for peace in the 1990s.
The DUP and Sinn Fein have spent years lobbying US business for investment in the region.
In 2007, the then DUP leader and First Minister, Ian Paisley, with Deputy First Minister Martin McGuinness were photographed ringing the trading bell at Wall Street in the first days of the power-sharing government.
In May 2008, the US-Northern Ireland Investment Conference brought industry leaders from 80 American companies to be briefed on investment potential in Northern Ireland.
By the end of that year Mr McGuinness, with the newly installed DUP leader and First Minister Peter Robinson, again visited Wall Street.
