So receivables were $17.1 million at December 2019 and we received $2.8 million in the March quarter 2020.
In contrast the receivables at December 2018 were $17.8 million and $7.5 million was received in January 2019 (and $10 million in the March quarter 2019).

The lags in Chinese paying have been discussed before. Can anyone recall the detail as I thought the lags had been reduced?

Robert's reply implies payment terms are still over 90 days. It also suggests the balance sheet was not strong as stated in the 5 March 2020 presentation if major payments were not expected this quarter. I wonder when they are expected.
