Khan, who returned home from India after failing to meet the top brass of the BCCI, asked the Indian Board to make its intentions clear about the proposed series in December in a week's time or else the PCB will take a call regarding its team taking part in the World T20.
India will host the World T20 next year in March-April.
He said already the ICC President Zaheer Abbas had raised concerns that if the current situation persisted in India, then there would be issues of guarantee of safety for players and officials in the World T20.
Khan, however, stopped short of ruling out any chances of the two countries playing the bilateral series in December in the UAE.
"We have not played them for last eight years and we have done well. So it does not make that much of a financial difference to us. Let us say if the series is held in December it will be a bonus for us," he added.
The career diplomat said the PCB would be writing to the ICC and the BCCI to register its displeasure over the way the PCB delegation was treated in Mumbai and New Delhi.
