The dollar rose to a near seven-week high against the yen on Tuesday as easing tensions over Syria and encouraging Chinese economic data eroded demand for the safe-haven Japanese currency.
The yen also weakened to a 3-1/2-month low against the euro, while the higher-yielding Australian and New Zealand dollars rallied as investors' appetite for risk increased.
Syria accepted a Russian proposal on Tuesday to give up chemical weapons and win a reprieve from U.S. strikes. The diplomatic initiative marks a sudden reversal after weeks in which the West appeared finally headed toward intervention in a 2-1/2-year-old war.
The dollar rose 0.8 percent to 100.32 yen, after climbing to 100.45 yen, according to Reuters data, the strongest since July 25.
The euro gained 0.9 percent to 133.08 yen, having reached 133.29 yen, the highest since late May.
The yen also weakened after minutes of the Bank of Japan's August policy meeting released on Tuesday showed members were confident that the central bank's aggressive monetary stimulus was helping to lead to an economic recovery.
The dollar rose 0.2 percent versus the Swiss franc to 0.9342 franc, but it fell against the Australian and New Zealand dollars. The Aussie hit a near seven-week high and last traded at $0.9313, up 0.9 percent. The kiwi rose 0.7 percent to $0.807.
The dollar index, which tracks the greenback versus a basket of six currencies, was flat at 81.80.
