LONDON, July 23 (Reuters) - British bank Barclays has raised its offer for ABN AMRO to 67.5 billion euros ($93 billion) and included some cash, helped by major investment from state authorities in China and Singapore.

Barclays said on Monday its new bid was 42.7 billion euros in shares and 24.8 billion euros in cash, up from its previous all-stock offer of 65 billion euros.

The new offer has been helped by an investment in Barclays of up to 13.4 billion euros by China Development Bank and Singapore state investor Temasek Holdings.

However, the new bid is still below a rival 71 billion euro bid from a group of European banks led by Royal Bank of Scotland , which is over 90 percent in cash.

"I think it's too low," said ING analyst Alain Tchibozo of the new Barclays offer. "It needs to be nearer 80 billion (euros). They need to make a difference."

Either offer for ABN would be biggest ever bank takeover.

ABN recommended Barclays' previous offer, but has come under pressure from some shareholders to be more receptive to the higher bid from the Royal Bank of Scotland (RBS) team, which also includes Spain's Santander and Belgian-Dutch group Fortis.

Barclays Chief Executive John Varley told reporters that ABN would look at share price reactions before deciding whether to back its new offer, but that he "hopes and expects" it will.

At 0705 GMT, Barclays shares up 2.7 percent at 732.5 pence. ABN AMRO was up 0.7 percent at 36.9 euros, RBS was up 0.7 percent at 614.5 pence, Santander up 0.4 percent at 14.03 euros and Fortis up 0.2 percent at 30.05 euros.

ABN said it would examine both offers in "a fair and transparent manner," but welcomed the strategic investment in Barclays from China and Singapore.

"The proposed strategic cooperation with China Development Bank further enhances the growth opportunities of the combined group in the attractive Asian market and can result in creation of additional long-term value for ABN AMRO shareholders," the Dutch bank said in a statement.

China Development Bank and Temasek will invest up to 13.4 billion euros in Barclays, with 9.8 billion euros of that conditional upon completion of the deal with ABN.

Under the deal, China Development Bank will take a 3.1 percent stake in Barclays, potentially rising to around 8 percent of an enlarged Barclays. Temasek will take a 2.1 percent stake in Barclays, potentially rising to just over 3 percent.

Barclays also said its earnings in the six months to the end of June rose 14 percent from a year ago to 4.1 billion pounds.
