An 85 page document sent to the WTO...indicates Kyiv wants to raise tariffs on more than 350 goods...worth $4.6 billion at 2011 levels.
But Kviv claims a willingness to negotiate and consult before enacting the tariff changes.
A diplomat believes the new plans on so many goods might force renegotiation on Ukraine's WTO membership.
"We don't know what is behind Ukraine's move," said a diplomat. "Maybe the financial crisis. Maybe political reasons. Maybe industrial."
