Argentina said on Tuesday it would meet with a mediator for the second time this week in the country's dispute with "holdout" investors, lifting market hopes for a deal needed to avoid another painful debt default. With the economy already in recession, President Cristina Fernandez's cash-strapped government has until July 30 to reach an agreement with hedge funds who refused to participate in the country's earlier debt restructuring and have been suing for full repayment of sovereign bonds which Argentina defaulted on in 2002. On Argentina's local over-the-counter market, benchmark Discount bonds ARDISCD=RASL rose 1.60 percent to 88.65 while Par bonds ARPARD=RASL were up 1.32 percent to 49.90. Traders cited optimism over the talks as the reason for the climb. Argentina's cabinet chief Jorge Capitanich did not say whether the holdout funds led by Elliott Management Corp and Aurelius Capital Management would participate in Friday's meeting. There
