The dollar trod water early on Friday as investors awaited a crucial meeting between the leaders of the United States and China at a Group of 20 summit over the weekend for any signs of progress to end their heated trade war.
The dollar traded at 107.73 yen , little changed on the day but on course for a 0.4% gain this week as the greenback mounted a recovery from a five-month low of 106.77 yen reached on Tuesday.
The dollar index (DXY), which measures the U.S. currency against six of its peers, was at 96.195, down 0.3% on the week.
The United States and China have already imposed tariffs of up to 25% on hundreds of billions of dollars of each other's goods in a dispute about China's trade practices that has lasted nearly a year.
The euro (EUR=) last traded at $1.1370, unchanged on the week. However, analysts say sentiment on the single currency remains weak due to speculation the European Central Bank will ease monetary policy.
Sterling was unchanged at $1.2670, on course for a 0.6% weekly decline on uncertainty about who will be Britain's next prime minister and on worries about whether the nation would be able to avoid a no-deal, chaotic exit from the European Union.
