David Cameron said Kazakhstan was "not just an emerging market" but "an emerging power" after signing a strategic partnership with the country:
We have agreed to open a new chapter in our relationship. The strategic partnership agreement that we have just signed will take our relationship to a new level.
A relationship based on strong economic ties, on closer co-operation on security and defence and on increasing links between our people.
The Government hopes the business deals signed on the trip will be the start of a surge in trade, which could result in contracts worth £85 billion in Kazakhstan over the coming years.
The Prime Minister's trade mission to Kazakhstan has been overshadowed by controversy over the country's human rights record.
David Cameron has arrived in Kazakhstan, becoming the first serving Prime Minister to visit the country.
