Cairo: The head of the political arm of Egypt's Muslim Brotherhood has hailed US-Egyptian ties during talks with the US State Department's number two, but also said they must be "balanced."

The meeting with Deputy Secretary of State William Burns on Wednesday at the Cairo headquarters of the Brotherhood's Freedom and Justice Party (FJP) came at the end of marathon elections that propelled Islamist parties to centre stage.

Washington has reached out to the Brotherhood in a nod to the country's new political reality, with Islamists poised to dominate the first parliament since a popular uprising ousted veteran president Hosni Mubarak in February.

FJP head Mohammed Mursi said his party "believes in the importance of US-Egyptian relations," but stressed those ties between the two nations "must be balanced," in a statement issued after the talks.

Mursi "welcomed" Burns's visit and "asked that the United States review its policies... in line with the (aspirations) of the Arab Spring" uprisings that brought down autocratic regimes in Egypt, Libya and Tunisia.

He also called on Washington to adopt a "positive position concerning Arab and Muslim causes," saying its policies in the past were "biased and not in its interest," an apparent allusion to strong US support for Israel.

In Washington, State Department spokeswoman Victoria Nuland said Burns was sounding out the Brotherhood's views amid concerns about its attitude toward women, minority Christians and Egypt's 1979 peace treaty with Israel.

"It was an opportunity to hear from them and to reinforce our expectations that all the major parties will support human rights, tolerance, rights of women and will also uphold Egypt's existing international obligations," Nuland said.

Nuland said Burns's failure to meet with representatives from the more hardline Al-Nur party, who claim to be just behind the FJP in the elections, should not be considered a snub.

"It was not a matter of excluding them. He was not able to meet with all of the parties," Nuland said, adding that US embassy staff did meet with Al-Nur, A Salafi group that believes in the strict implementation of sharia law.

Wednesday's meeting comes as Egyptians voted in the final phase of staggered elections to elect a lower house of parliament. Polls closed at 2230 IST.

Egypt's two main Islamist parties have obtained a crushing lead in the seats declared so far, reflecting a regional trend since Arab Spring uprisings overthrew secular authoritarian regimes.
