The Duke of York attended a Southeast Asian Leaders Summit in Thailand as part of the start-up mentoring program he founded.

Andrew was seen at the Association of Southeast Asian Nations (ASEAN) summit held in the Thai capital Bangkok on Sunday.

The 59-year-old royal attended the conference as part of Pitch @ Palace, an entrepreneurial support organization he founded in 2014.

Pitch @ Palace has helped 931 technology start-ups to date and provides mentorship and links to potential investors.

Andrew arrived at Bangkok’s Suvarnabhumi Airport on Saturday and was greeted by British Ambassador to Thailand Brian Davidson and Jirayu Isarngkul Na Ayudhya, Privy Advisor to the King of Thailand.

On Sunday morning, Andrew attended a preparatory event for the Pitch @ Palace initiative ahead of a business pitch competition to be held on Monday.

The conference will hear pitches from a number of entrepreneurs and the start-up with the best pitch in the competition will then travel to St James’ Palace on December 11.

After the Sunday morning event, Andrew visited the ASEAN Business and Investment Summit at the Impact Exhibition Center in Bangkok.

The event’s agenda included international trade, sustainable development and the future of industrialization.

The Duke of York’s appearance at the event comes after he made international headlines over the summer because of his ties to disgraced financier Jeffery Epstein.

The ASEAN summit also featured meetings with world leaders and a speech by UN Secretary General Antonio Guterres on the plight of 730,000 Rohingya Muslim refugees from Burma.

ASEAN leaders meet annually to discuss policies on pressing issues while maintaining a policy of non-interference in the affairs of their neighbors.

Andrew has been criticized for his connections to Epstein, who was found hanged in his New York jail cell on August 10 as he faced charges of sex trafficking and conspiracy.

The Duke categorically denies any wrongdoing.

Buckingham Palace was also forced to strongly deny allegations made by Virginia Roberts in court documents in Florida that she was forced to have sex with Andrew when she was 17, which is lower than the age of consent in the state.

The palace called the allegations “false and unfounded”, saying “any suggestion of impropriety with underage minors” by the duke was “categorically false”.
