The EU has agreed to widen sanctions on Zimbabwe.
According to one diplomat there has been an agreement in principle on reinforcing the sanctions.
It is expected to be formally approved on Tuesday.
It will include travel bans and asset freezes on a larger circle of officials and supporters of President Robert Mugabe.
A further review in September would examine whether more measures were needed.
Meanwhile, negotiations to resolve Zimbabwe's deep political crisis have stalled after opposition leader Morgan Tsvangirai refused to sign a framework for talks.
Both Mr Tsvangirai's Movement for Democratic Change and the ruling ZANU-PF party of President Mugabe are under strong African and world pressure to negotiate after the widely condemned re-election of Mr Mugabe last month.
The two sides began preliminary talks under South African mediation last week.
