The meeting, held earlier today, was attended by three members of the Delhi Congress, led by DPCC chief Ajay Maken, among others. The BJP did not take part in it.
Addressing a press conference after the meeting held at the chief minister's residence in Delhi, Mr Sisodia said Mr Maken had assured them that Congress lawmakers would raise the sealing issue in Parliament along with Aam Aadmi Party lawmakers.
Hitting out at the BJP, the deputy chief minister said it was unfortunate that the saffron party's representatives did not attend the all-party meeting called to find a solution to the sealing issue which has caused problems to the city's traders.
He alleged that through the sealing drive, the BJP wanted to pave the way for foreign direct investments in retail in the national capital.
"In today's meeting, it was decided that the all-party delegation will meet the monitoring committee to find a solution to the sealing issue," Mr Sisodia said.
Health Minister Satyendar Jain, Development Minister Gopal Rai, AAP leader Sanjay Singh and lawmaker Somnath Bharti were among the others who took part in the talks.
Mr Maken also attacked the BJP for boycotting the meet.
He said the Delhi government had not yet met the monitoring committee since the sealing drive had begun, adding that the chief minister had also agreed to a meeting with the committee.
Mr Sisodia said the BJP could resolve the issue immediately if it wanted to.
"The BJP has the government at the Centre. They want to finish off traders so as to bring in FDI," he said.
The sealing drive -- shutting of illegal establishments -- started late last year on the directions of the Supreme Court-appointed monitoring committee.
