Loan recovery from a business person

Hello, I had loaned some money to a person who is currently in Singapore but is of Indian origin and a native residence of Mumbai. He needed the money to do promotional activities for his business. We had an agreement on the amount to return and the duration of the loan. This person asked for an extension to the payment stating business issues and recovery from the market. He was constantly dropping names of his connections and assured me the money will be returned by the extended date. This drama continued for many months and I started pressurizing him to return the money. In the last 30 days, he committed to pay the interest amount and there were three incidences when he had defaulted on his commitment. I would like to know my legal options in order to recover the interest that we had agreed on. regards Snehal K.
