This is from an article in The New York Times.
Mr. Moon has been pressing Pyongyang for months to send a delegation to the Winter Olympics his nation is hosting next month. The proposal was effectively ignored until Mr. Kim used his annual New Year’s Day speech to signal he was “open to dialogue” with the South to discuss easing military tensions on the Korean Peninsula, as well as to sending North Korean athletes to join the Games.
Do we need 'to' before 'sending' here? The reason I am asking is that I read the last part:
he was “open to dialogue” with the South to discuss easing military tensions on the Korean Peninsula, as well as (he was “open to dialogue” with the South to discuss) sending North Korean athletes to join the Games.
If my way of reading is right, then I thought there shouldn't be 'to' before 'sending'.
