Russia promised at the talks in Istanbul to drastically scale down its military operations around Kyiv and the northern Ukrainian city of Chernihiv, while Ukraine proposed neutral status with international guarantees.
The US dollar was lower, while the yen staged a modest rebound after tumbling on Monday to its lowest level since August 2015.

The euro was up 1.3% at $1.1125, at its highest since 18 March.

Versus a basket of currencies, the dollar was down 0.6% at 98.470, but not far from its highest level since May 2020 at 99.415.
The US dollar fell 0.9% to 122.7 against the yen after rising to its highest level since 2015 on Monday. It is set for its biggest monthly rise since November 2016.
Japanese Finance Minister Shunichi Suzuki said the government would closely watch currency moves to prevent a "bad" weak yen that hurts the economy.
"While the comments from Japanese officials overnight are unlikely to reverse the yen weakening trend on their own, they should at least help to slow the recent fast pace of yen selling," Lee Hardman, currency and emerging market analyst at MUFG, said in a note to clients.
The Bank of Japan today kept up its relentless quest to defend a key yield cap by offering to buy unlimited amounts of 10-year government bonds, putting even more downward pressure on the yen.
