The International Monetary Fund said Saturday it had reached a preliminary agreement with Ukraine that could see the war-scarred and cashed-starved nation receive fresh aid in the first half of the year. The news was particularly good for the ex-Soviet republic because the IMF statement referred to a loan of $1 billion (0.9 billion euros) and not the lesser sums discussed in earlier months. Ukraine also gets the reprieve of not having to go though the unpopular measure of raising its pension age to get the cash.
