Deputy Prime Minister and Foreign Minister Don Pramudwinai met Thai-born US senator Tammy Duckworth and US Secretary Of State Antony Blinken to discuss the US' intention to donate 1 million more doses of the Pfizer Covid-19 vaccine to Thailand.
The talks were conducted in Washington DC on Tuesday during Mr Don's visit to the US for the 76th session of the UN General Assembly (UNGA 76) in New York City.
They follow last week's claim by Khunying Sudarat Keyuraphan, a former key figure in the opposition Pheu Thai Party, that Ms Duckworth told her the delivery of the vaccine couldn't be completed due to a delay in Thailand's handling of the paperwork.
The Thai government and the US embassy in Thailand have denied the claim.
At the meeting with Ms Duckworth, Mr Don thanked her for pushing for the additional donation of 1 million doses of the Covid-19 vaccine.
He said the Thai and US sides will meet next week over the matter.
On July 30, the first batch of 1.5 million doses of donated Covid-19 vaccine, manufactured by Pfizer-BioNTech, was delivered to Thailand.
Mr Don also expressed his gratitude through Mr Blinken for the US plan to donate more Covid-19 vaccines to Thailand as well as the other assistance the US has offered in the battle against the Covid-19 pandemic, said the Foreign Affairs Ministry.
Mr Don also met Kurt Campbell, the Indo-Pacific coordinator in the US National Security Council, for discussions about Thai-US cooperation in improving Thailand's access to the Covid-19 vaccines, said the ministry.
During his meeting with Ms Duckworth, Mr Don also discussed several other matters including possible Thai-US cooperation to revive the economy hit by the pandemic, the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and the Free Trade Area of the Asia Pacific (FTAAP), said the ministry.
Other topics discussed during the meeting between Mr Don and Mr Blinken included the 26th UN Climate Change Conference that will take place in November, at the Scottish Event Campus (SEC) in Glasgow.
